I'm not an expert on land records, but yes, he could have been living in Little River Co, AR when he sold land in Sevier Co, AR.Go over that record, it usually will state where the buyer and seller each resided.I've seen records where the seller lived in another state.That record should also be recorded in Sevier Co, AR, too.
Have you checked the Little River Co, AR GenWeb site?I see a bride M.E. Rainey md 1889 to A.J. Davis.That could be the Mary E. Rainey, dau of A.J.,who was 9 yrs old on the 1880 census.She would be about 18 in 1889.Looks like the Rainey family was living in Little River Co, AR in 1889.
They have a list of volunteers who will do specific lookups, maybe one could check cemeteries for you???
You say you are looking for your elusive Andrew Jackson, you did find him living with what probably is his widowed mother on the 1860 census in Red River Co, TX, right?
I noticed on the 1880 census his oldest children were born in TX.Checked the 1870 and there he was with what looked like two brothers living next door.Sure nuff, all three are on the 1860 with their mother.She was born in NC and oldest children in AL.She owns land, have you checked out land and probate records for Red River Co, TX to see who the father was?
Also, check for guardianship records in Red River Co, TX,yes even though their mother was living.Her husband left minor children, and the court would appoint a guardian,not to physically take and raise the children, but to report back to the court of any sale of the estate.That was to protect the interests of those minor children.I don't know when the courts began "allowing" the mothers to be that guardian.I have one in Wilbarger Co, TX 1889 that was made the guardian of her own children.
