Hi! I have just acquired a photo of Warren Barker and his wife Hannah McCabe. I am also a descendant of his born-out-of-wedlock son William Grant Barker (I have a few pictures of him as well). You are from Lula's line (I believe I have some of her as well), and I am the great-granddaughter of Henry Barker, the baby. If you still check this, please send me a message! I'll gladly share any photos or info I have, and I'd love to see/learn anything you have as well!!!
(This is for anyone interested!)
