I am the person who originally posted the info on Ancestry; He's in my direct blood line. We know his dad was John, who added Sr, after his son John, Jr, was born. Think there were 2 wives, but don't know which kids belong where. I have documentation on Ancestry of Alexander to present, in a public tree. If you are not on Ancestry, please email me and I will be glad to share anything I have.
Wife - Harriett Stewart
Possible wife: Mary Morrison Gray
Daughter Mary Morrison Cummins
Sons: Alexander Gray went to AR; 4 kids to TX, then Greer County, IT (now Harmon Co, OK)
John, Jr - became the miller at Cummins Falls, TN
David - went to Texas
(Please put "Alexander G CUmmins" in the subject line so I don't discard.)
(We have documentation that he was married to Harriett Stewart.)
