I've been digging in my roots and have found a couple of interesting "facts".

The only pre-Revolutionary war immigrants in my family (so far, I've not gotten to everyone) came immediately following the Revolutionary war and that is my Scottish and German connection. Paternally, I only have one Scottish ancestor in the last 8 generations or so, an Urquhart woman married my great, great, great, great, great grandfather. I have found other Scots maternally (a McKaye and a MacIntyre) but they also were women, that married men in my line, and they were in the 1600's or so.
You can only go so far before hitting a brick wall. I'm stuck on a handful of lines and am considering getting a paternal test kit for myself as well as a maternal kit for my sister.
