I have a copy of the Walker Family Album Published by the Washington County Historical Society in 1964. I also have several other booklets that were also published on the subject. David Walker was my Great/Great Grandfather and E.H. Walker was my Great/Grandfather. I have alot of info. on the Walkers that I would be willing to share. You could also contact the Special Collections Division of the UofA this is available online. If I can be of service let me know.
