Late comers to Ireland, Irish history:
*Fomorians/Cessair, 6,000BC
*Partholonians
*Nemedians
*Firbolgs
*Tuatha De Danann-1880-1700BC
*Milesians(Queen Scota)
*Celtic/Gaels - 600-150BC
This entry is interesting, because it is often interpreted as meaning "Tribe of Dan". (But there are other interpretations too.)
Parts of the Tribes of Dan, Asher and Judah bailed out of Egypt about a hundred years before the overland Exodus. That would put their "exodus by sea" around 1600 BC(?????) or so. Now if you could get these dates to move a little bit we might have another confirmation.
The Milesians name comes from Spain, and those Spaniards are the source of our word "militia". How does this fit in with those extensive Spanish Celtic communities and the frequent travel between Spain and England and Ireland???
