I think I may have some information. I am a decendant of a Willam Alfred Jenkins and Eunice Parks. I have their children as being a John Jenkins, Turner Jenkins and William Alfred Jenkins. My line stems from the latter WA Jenkins. However, I am now not sure where my information came from with regards to Turner and John. I still need to verify. Though with you searching for possibly the same people I may have just received my verification. :)
Let me know if I can provide any more indepth information for you about this line.
