Hello, I've been doing some research on my line of O'Liathain's (Lane/Lawn/Lyon) from Donegal and just wanted to get some opinions on what I've found.  My surname is Lane, and my ancestor, according to family lore, left Ireland for Virginia from the port of Derry circa 1740. I've found that some of the Irish Lane/Lawn/Lyon's from Donegal/Derry, which is where my ancestor was from, are believed to be descended from the O'Liathain's, a sept of the Ui Fiachrach Muaide originally from north Connacht. These O'Liathains were in very early times seated in the parish of Dromard in County Sligo. According to O'Clery it seems that a branch of these O'Liathians, along with a branch of O' Dubhda (O'Dowd/O'Duddy) moved north and settled in the Kingdom of Tirconnell. The Ui Fiachrach claimed to be descendants of Fiachra, son of Eochaidh Muighmheadhoin, King of Ireland in the 4th century. Fiachra was a brother of Niall of the Nine Hostages and father of the celebrated King Dahy, the last pagan monarch of Ireland. The Ui Fiachrach were divided into two branches, viz: Ui Fiachrach Muaide and Ui Fiachrach Aidhne. My question is since these O'Liathains and O'Dubhda's of the Ui Fiachrach claim to be of descent from Niall's half brother Fiachra, and since both lines have tested M-222, could this possibly explain my early Lane ancestory? All the best, Chris Lane
