Taylor, Harrison, Sutherland, and Hall info is available right here in Fairfax, VA.  Most of this I've gotten myself, though much help has come from Kitty (distant Sutherland cousin) and Cindy (a cousin I met at the Fairfax Court House--fate?), and can't forget Diana!

The Cook research I have done myself, with lots of help from my Grand Uncle Harold.

Much of the Scates research I received from Betty Haney at GenForum.com, but I made sure to confirm through various state records.

Bowen research is sketchy, but, again, I've gotten the info both from Betty and state records.

Dillard research is getting better...I think I've found the elusive parents of Elbert Dillard right here in Virginia (Washington Co.)

Most of the Seats info has come from Tracey Bradley (I downloaded some info from Rootsweb) not sure how accurate it is, but we can give her the benefit of the doubt since she lives in TN and I don't—she has better access to records than I do.

The Stout info started through various genealogical websites.  As I go back and check through marriage and census records, a lot of it has turned out to be wrong.  So I have to go with the official sources...let me know if I'm headed in the wrong direction on any of this stuff.
