Sara Anna Adair and William McTyer and their family are discussed in great detail in Kinfolks, volume 2 beginning at page 1299. There is quite a bit of info there, but in a hasty reading of it, I did not find the names you mentioned. I suggest that you get it from the library and read it more carefully than I did. It certainly should be a good starting point for you. Sorry I don't have any better info.
