I found this in an account of my Watson line -- I don't hink it is accurate in regard to my ancestor, as he was born in Ireland in 1740, but it probably has some basis in fact. "Soon after the battle of the Boyne 1690, owing to the religious intolerance and dissension, the Watson family moved from Scotland to County Tyrone, Ireland. How long they remained I do not know, probably not long for in the early part of the eighteenth century, presumably in 1729, when the great tidal wave of immigration crossed the Atlantic from Scotland and Ireland, they came to America and located for a season in Franklin county, Penn near where Chambersburg now stands. This was during the old French Wars 1740-1750. Here they were greatly harassed by the Indians. During the wars a few years later they moved to the Carolinas. Our direct line remained in Pennsylvania."
