Edwina Williams in California has a great deal of information on the Olvey family..you might want to check with her for information. If you haven't been in contact with her before, please send me an e-mail and I'll look up her e-mail address for you.
I am a descendant of Wiseman Olvey and Edwina has told me that Leonard Sale was Mary Sale's father.
Using "FamilySearch" a few weeks ago, I found the following information (this wasn't MY research...but someone else's...you may want to look-up "FamilySearch" yourself to investigate on your own!)
