Good Evening Linda,
I have just started researching the Alexander tree for my daughter. Her connection started with her great grandmother
Martha Elizabeth Alexander, she married Murray Averett. Both are buried in Utah and therefore she has a link to the LDS folk. There is much information on line at Ancestry.com and Family Search.org, but as you also know not all of it is correct. I am impressed with your research and that was several years ago.
I was wondering if you have a copy of Angus' will handy if you would e-mail me a copy. I would be very interested in reading it.
Also I was wondering if you have ever found Angus father, the familysearch.org site has it as Jesse. However, I do not feel that is correct. Also tonight I found an Angus Alexander coming to American in 1766. The list is the bonded passengers coming to America. Have you heard of that?
Before this gets much longer and you get bored I should sign off. Hope to hear from you.
