Hi Steven,
I have a copy of the book The Family and Descendants of Captain John Autry by Mahan Blair Autry, Corsicana, Texas, Mar 15, 1964. Unfortunately, there is no index to this fine book.
However, on page 7, #6: Captain John Autry moved to Georgia and bought 100 acres of land on Beaverdam Creek, oct. 15, 1773 and was killed by Creek Indians near Skull Sholes Feb. 2, 1788. He and his wife, Elizabeth, had 8 children:
Alexander Autry, b. North Carolina
Martha Atury, b. North Carolina
Elizabeth Autry, b. North Carolina
John Autry, Jr., b. North Carolina
Solomon Autry, b. North Carolina
Agnes Autry, burn Georgia
Priscilla Autry, born Georgia
Jacob Autry, b. Georgia, 1780
From here, the book goes to Jacob Autrey, born in 1780 in Wilkes Co. Ga. on Beaverdam Creek.
Since the book has no index, it is very difficult to research it for individuals, but the book seems to pick up on the above Jacob Autry. I attempted to skim the book, but it seems Alexandria was not included in it and Jacob was the main focus of the research.
I'm sorry there wasn't more information in the book for you, perhaps someone else will be able to provide more information for you.
