I found this post from several years ago, and I am interested to find out if you know of any connection between your great grandmother and an individual named Albert Walker.
I am pretty sure that my great, great grandmother is buried in Bradley Cemetery as Susan Ann Holmes. However, I believe here first husband to be named Albert Walker. I'm finding it difficult to come up with any information on him. I believe him to have been born in Tennessee and died around 1870 maybe in Missouri.
