For every question that you think you have answered when doing genealogical research, two more questions will arise. It's sort of like courtship....the chase is often more satisfying than the capture! :-)

There will come a point when you might want to pursue two avenues of research to try to gain actual documentation. I would recommend that you take a look at:

New England Historical Genealogical Society (www.americanancestors.org) since many of our Scots ancestors entered the U.S. through the original Massachusetts Bay Colonies, such records as might exist of their earliest days in the New World may well be located there.

To do research in Scotland, try their Scottish National Archives at www.scotlandspeople.gov.uk

Be prepared for some "interesting" twists and turns....in one of my own lines I found that a Captain Thomas Erskine Askey had led a company of militia in the state of Massachusetts during the American Revolution. He had arrived in New England as a young chap under a contract of Indentured Servitude. Turns out that this chap was actually born in Ireland under the name of Thomas Erskine. His nativity in Ireland was due to his father having been spirited away to the Emerald Isle by his grandfather to escape the wrath of the English crown following the "rising of 1715'" that the grandfather had played a rather significant role in from his own origins in Renfrewshire. It took several years to piece all of that together....but the two sources above were invaluable in the doing of it. It's out there somewhere, just waiting to be found....

Good hunting!
