Presbyterians who were transplanted from low-land areas of Scotland to Northern Ireland (Ulster) in the 1600s and then immigrated to America in the 18th century.
Areas of Specialization
Americans have migrated so much throughout history that professional American genealogists are relatively adept at researching almost anywhere in the 50 states. This is especially true given the recent explosion of Internet access to various ancestry records (e.g, vital records, census data, military files, wills & probate documents, land records).
With that being said, I have more experience in northern states than southern, and am particularly knowledgeable about the states of Minnesota, Michigan, Ohio, and New York. Areas of specialization include: Scots-Irish, Norway, Quakers, and Military History.
