I wonder if there were two people with the same name (Andrew Jackson Isacks/Isaacks)? My 2nd great-grandfather was Andrew Jackson Isacks, born in 1825, and only 10 years old at the Siege of Bexar.
I am interested to know more about your husband's ancestor; I didn't know of this sister (Mahala Isaacks who married Hardy Pace).
