There are really serious problems in following some of the lines back any distance at all, but there were Poages and Terrills and others to pursue, and recently I have been doing just that. Early on in this process, I found a Poage genealogy on HeritageQuest Online, and ordered the hardcopy from Higginson. Yesterday, I made a concerted effort to find out where the Brothers Poage came from before they were early settlers in Augusta County, Virginia.
Yeah, well, I should have seen this coming: they came from Ireland, but they weren't really Irish. They were part of the Scots who were in Ulster for a while and then left in a massive series of waves of emigration. This leaves me, then, with at least three distinct groups of early arrivals to what became the US: the Dutch Colony (a two part group including Dutch people and Germans from the Palatinate), Scots-Irish arriving in Philadelpha, Pennsylvania and then moving to points inland, and Virginia (I've got a bunch of arrivals elsewhere in Virginia in addition to the Scots-Irish -- including a Dutch guy).
In addition to the obvious effects (oh, look, a whole lot more genealogy reference works to order. Joy.), this has offered me another way to contemplate structuring a book about genealogy: The Story of X as told through Lineages A1..ZN. Anyone can do this -- everyone came from somewhere, and if they really did spend a thousand years in one village, that's a helluva story all by itself. For my grandmother, it's truly the story of American migration: _to_ the Americas and then _within_ the Americas.
I guess I'll just keep poking away at it and see what I think in a few weeks. When I know way more about the South than I ever intended to.
Oh, and judging by the Poages, I'm also going to be learning a ridiculous amount of military history as well.
