The Phoenicians were people of the sea and considered to be the first merchants having settlements and trade routes spanning from the Middle East, to Ireland, and the West Coast of Africa, dealing in commodities and slaves. They would sail the Mediterranean to sale trade goods; these sailors were sellers. Merchant has the root word mer referring to the sea like a mermaid. They are believed to have brought with them an alphabet that would evolve into many other alphabets such as Greek, Latin, Cyrillic, Hebrew, and Germanic Runes.  They also may have given new vocabulary and syllables along with their alphabet. It is possible they had trade routes that went around the South of Africa to India, China, Southeast Asia, and Australia.
It is believed that the Phoenicians originated in the Levant, Modern day Lebanon, formerly known as Canaan.  The word Phoenicia means land of the purple people  and is an ancient Greek term alluding to the color purple-red, phoinix/phoenix , referring to a dye harvested from murex mollusks, Tyrian (Royal) purple, that was a major export also known as Phoenician purple. In the ancient Phoenician city Carthage, in North African, they were known as Punic/Punicus/Poenicus. 
Since they were in contact with so many different groups of people it is probable that they would cause trouble for one group while making it appear as though they were attacked by a different group instigating war so they could benefit from the increase in needed goods from both sides. They were both traders and traitors. They were also known to trade in slaves with the Greeks, Romans, and North European Germanic, Celtic/Gaelic, and Balto-Slavic tribes.
In Irish mythology the indigenous people are called the Fomorians described as monsters and the destructive gods. Examining the origin of the term Fomori there are multiple possible meanings. The first part fo is commonly believed to be from the Old Irish for below, beneath, lower, under, or nether. Thinking of nether (Dutch: neder ) recalls the Egyptian word for God, NTR, possibly pronounced like the English nature and may be etymologically linked to the Arabic word nakira, meaning “the unrecognized”, Islamic Angel Nakir, “the denier”, Hebrew nakar, “to recognize, acknowledge, know, respect, discern, regard; to act or treat as foreign or strange, disguise, misconstrue”, and the term from the Ethiopian language, Grezec, nakar meaning “strange, foreign, stranger, alien, who is not a relative, other, different, unusual, wonderful, marvelous.”    The next part of Fomori is debated between the Old Irish mur meaning the sea, mór meaning great or big, and may be refer to a demon or phantom connoting The Morrigan from Irish mythology and cognate with the English mare as in “nightmare” , also similar to Moirai, the Greek sisters commonly known as “the Fates” [11a]. Taking this all into consideration Fomorian may mean “the wonderful strangers that come from beneath the sea” and since the Earth is a sphere people sailing from far away would appear to come from “below the sea” and they probably came from the West, the direction the Sun sets into the underworld, thus their connection with dark forces coming from the nether realm. They are possibly connected to the Phoenicians as for they are the “mer people.”
The Tuatha Dé Dannan (named after the Irish Mother Goddess Danu [11b] ) were at war with the Fomorians in the myths. Lugh, the grandson of the Fomorian King Balor, became king of the Fomorians and killed his grandfather, winning the war for the Tuatha. The names Tuatha Dé Dannan and Fomori may actually be describing two halves of one family fighting over claims to the Kingship. The Fomori are probably synonymous with the Norse Jötnar and that would mean the Tuatha Dé Dannan are the Æsir lead by Odin or O’Don/Dan, like the Irish Royal family O’Donnell that comes from Dòmhnall, meaning “world ruler.” The letter “O” is sometimes used as a prefix to mean “the”. Donnell appears to be a compound word of Don, “ruler (like the leader of the mafia,the Latin dominus ‘master/owner’, the Hebrew Dan ‘judge’, and the English/French Doyen ‘respected, prominent, or senior member of a group’ the source of the word Dean [11c] )”, and El/Al/Ell/All, “god (such as the Hebrew: Eloah and Arabic: Allah”, so together Donnell means “the ruler god”  The O’Donnell Dynasty ruled the Kingdom of Tyrconnell in Northwest Ireland, present-day County Donegal in Ulster.Tyrconnell is said to mean “Land of Conall”, but the first part Tyr is Old Norse for “a god” and the name of the older supreme God of the Norse before Odin [12a] and the capital city of Phoenicia was Tyre. [12b]
The Phoenicians and Fomori may also be connected to the Moors of North African Mauretania also called the Mauri/Berber. In the 900s BCE the Phoenicians named the Western most cost of North African Mauharim, meaning “Western land”.   The name Mauri brings to mind the Polynesian people called Māori/Moriori.   There are also people in the American Ouachita River Valley that call themselves Muurs and believe they came from the mythological Motherland, Muu.  The name for the statues of Easter Island, the Moai, may be remnant memories of Mu.
All these interpretations of the land Mu/Lemuria might all be correct, but as one large continent, even connecting to the Americas. In Irish mythology, the Tuatha Dé Danann, came to Ireland from four islands to the West, one of which was named Murias/Muirias.
In Hindu, Jain and Buddhist cosmolgy there are references to the mythic Mount Meru/Sumeru. [17a]
“It is curious that the island named Murias should be so similar to Lemuria. If we take the letter ‘L’ to represent ‘the,’ then L’muria is undoubtedly the Murias of the de Danann.” -Michael Tsarion, The Irish Origins of Civilization Vol.1, Chapter 4 The Atlanteans Arrive.
There are more groups of people with names that appear to come from Mu/Mur/Mer/Mar/Mor:
—Maouri- Niger, West Africa 
—Muria- Chhattisgarh, India, Bastar district  “Muria comes from the root word mur, which can be translated as either “root” or “permanent”; it may be based on the fact that the Muria are settled, unlike the nomadic Maria.” [19a]
—Mari- Mari El republic, Russia 
—Amorites/Amurru- Ancient Mesopotamia, Phoenicia, Canaan 
—Sumerians- The people of ancient Mesopotamia, believed to be the originators of culture, religion, and science. [21c]
—Merovingian Dynasty- Ruling family of the Germanic Franks (French) from 5th to the 8th centuries. [21h]
—Muslims- Followers of the religion, Islam.
The Amorites, also called MAR. TU/Amurrum/Tidum/Amar/Emori, are mentioned in the bible as descendants of Canaan, the son of Ham. The King of the Amorites, King Og, was said to be the last of the Raphaim (poosibly giants) . The Amurru Kingdom was named after the god of the same name, Ilu Amurru/Martu , that may be cognate with the Roman/Greek Mars/Ares and the Sumerian Marduk.  The capital of the Amurru Kingdom was Mari in modern Syria.  [25a] In South America, Peru there is an archaeological Inca site called Amaru Marka Wasi (Temple of the Moon)  named after the two-headed dragon Amaru   and is probably synonyous with the Mayan Kukulkan, Atec Questzalcoatl, and the K’iche’ Q’uq’umatz, the Feathered/Plumbed Serpent.    Also the area of France that includes the Brittany Peninsula was called Armerica in ancient times. 
Another interesting possible connection between America, Europe, and the Middle East are the names for the Proto-Greeks the Danaoi/Danae/Danoi/Danaans , the Navajo Diné , the North European Danes/Vikings, the Israeliste tribe of Dan, the Southeast Anatolian Danuna [34a], and the early name of Southwestern England Dumnonii/Danmonii   . The United States city Des Moines, Iowa also comes to mind. All these names have the Indo-European root danu meaning moisture, dew, water, or river.  Dunmnonii might mean “the dwellers/rulers of the deep”. The modern Devon/Devonshire (formerly Denshire) derives its name from Dunmnonii (the shift from “M” to “V” is a typical Celtic consonant shift). The capital city of Scotland is named Edinburgh (Gaelic: Dùn Èideann) coming from the older Din Eidyn(Eden), associated with the Gododdin kingdom and appears to be named after Odin. The words Celtic: dùn, din, and Old English burh means “fort”. There were also people called Damnonii/Damnii in Southern Scotland, supposedly different from the South England Danmonii.
“The early name of southwestern England was “Dumnoni,” or “Danmoni,” as shown by a portion of a map in Celtic scholar, John Rhys’ book, “Early Celtic Britain.” This comprises today the British counties of Cornwall and Devon. Highly respected historian William Camden remarked concerning Cornwall: “That region, which according to the geographers, is the first of all Britain, and… was in ancient times inhabited by those Britons, whom Solinas called, Dunmonii, Ptolomy (called) Damnonii, or (as we find in some other copies), moretruly Danmonii derived from the tin mines of the area. The British call it Moina” (Britannia, p. 183). This compound word is therefore composed of “moina,” a tin mine, and “DM” or ‘DN which stands for money, blood or lord for the people who mined the tin. So this most ancient region of England is properly called “DNMN,” meaning, “THE BLOOD OF MONEY = TIN” or the “LORD OF MONEY = TIN.” –https://phoenicia.org/Phoenician-Celtic-connections.html
In ancient Egypt the mysterious term “Sea Peoples”  is used to describe multiple groups of people. There are several theories as to who these people truly were.
—Teresh- Possibly the Tyrrhenians , sometimes called Spard/Sard, sometimes idetified with the Etruscans, and may be associated the ancient city Troy in West Turkey. Sard recalls Sardinia, also the Sarmatians a tribe from the Eurasian Steppe. [45a] Spard brings to minds the Sephardim the Spanish Jews. [45b]
The Trojans were assiociated with the Dardanoi/Dardanians/Dardans  named after the son of Zeus, Dardanus , the founder of the city of Dardanus  on the Troad penninsula in the Dardania district of West Anatolia/Turkey. According to Virgil’s Aeneid, Dardanus was a Tyrrhenian prince. In the Balkans there was also a people called Dardani  and the kingdom of Dardania.  There was also an Assyrian people called Dardanean by Herodotus. 
In the 17th century a group call the Dönmeh formed in Turkey. The Dönmeh, meaning “convert” in Turkish, are a Jewish group that publicly converted to Islam, following their leader Sabbatai Zevi, the self proclaimed Messiah of the Jews converted to Islam due to threat of death by the Ottoman Sultan Mehmed IV. [51a] [51b] [51c]
Is it possible that all these people were founded by the same people or at least effected by the same people, with the only remaining memory being in their names?
