Eleanor, (I tried to send this to you direct, but the email came back as "undeliverable".)
I just recently solved the puzzle that the "Jack" Alexander my grandmother's notes had listed as her great great grandfather was John Garrison Alexander.Which in turn led me back to the Rev. James Alexander, and now your posting.
He was my 9th great grandfather and I descend from his son Joseph.I would appreciate anything you could share with me as I only have a direct line with no other children until I get down to John Garrison Alexander. I will be happy to share any information that I have with you.
Thank you for your time and I hope to hear from you soon.
