I have a book compiled by L. Maud Anderson Graham and James M. Anderson with what seems to be detailed info on James and Isabelle Anderson's descendents starting from their son, William's immigration to America. My great-grandfather was William Anderson, son of the Wm. Anderson that immigrated to America in 1829. I would like to share the information that I have (I am just starting out in genealogy, so I haven't really gone through the book in detail, but the earliest I got was James and Isabelle). Please e-mail me! I am in Columbus, OH.
