We have an Andrew Jackson Sides in our family history. There are some similarities. We have a copy of a birth certificate for Thomas Jackson Sides, son of Fannie Evans and Andrew Jackson Sides of Myrtle Springs, Van Zandt Co, TX. The birth date for Thomas is Dec 3, 1876; Andrew's age is recorded as 24.
I can try to email you a copy of this document if you would like it to compare to your records.
