I am trying to trace my first ancestors that migrated from Scotland to County Antrim, Ulster, North Ireland in the 1600's (or early 1700's) and later to the United States. I don't know where in Scotland they were from, but being that they were Presbyterians, the history books indicate that they weer part of a migration of Lowland Scots promoted by the English to reopoulate North Ireland with non-Catholics and cheap labor for the plantations .

As I mentioned, I do not know the name of my ancestors that left Scotland, but they had at least one child in North Ireland, George Alexander, who married a Jean/Jane McCord there.

I have no idea on where to start looking for records of this migration. Are there any good sources on this, where I can start looking for possible information on my Alexanders. POssible records that I am interested in are ship records, indenture contracts, tax records, etc.
