Rhonda, It's the family "back of" William and Mary that I'm cautious about -- her maiden name and his parentage. I'm suspicious about similar or look-alike information being grafted on to run back the chronological record without good evidence of tie. Scottish vs. English and confusion of Gadd(e)y and Geddy (who co-existed in Old Blisland) are the result. As a result, we have convincing-looking Scottish ancestry records posted on the Internet by adopting those "look-alike" data...and ignoring the conflicting English data. After many years, I feel reasonably confident of what we have for W&M "on down," and "The Gaddy Book," as I've called it, has the best account and most balanced treatment I've read anywhere.
Corinne was quite clear that family researchers should feel free to copy and circulate pages from the book, so, if you can "hook on" to the information published, that much of your research is "free" and up to you to extend. I just wish they were still with us to re-publish and update in a new edition, for they were wonderful people!
