The info I have says Grady's mother's name was Eula (or Eulah) Sykes. I found a "delayed" birth certificate for Grady that said Eula wasn't married when she had him, thus the last name Sykes. Eula's mother's name was Sallie. So here's how we're related: Eula had a brother named James Henry Sykes. James Henry had a son James Gailey who was my father. Your grandfather Grady was my father's cousin, and your father (if he is Grady's son) is my second cousin. That makes you my second cousin once removed.

She said:
I have heard 2 stories about Eula,,, she became pregnant by a fellow with the last name of Luck, not married her parents took Grady and raised him as their own, when he became about 8 yo Eula was married to the Luck man and wanted to take him back, they said no, my dad told me Grady was treated awful because he was the Bastard child:((( the other dark second story is Eula became pregnant by her own father!! And the Luck guy story was a cover story.

I responded:
1910 census shows Eula living at home with her parents and siblings. No Grady is listed, even though he had been born. 1920 has neither Grady nor Eula. 1930 has Grady (21 & single) living with grandparents but listed as son. 1940 has Grady married, still living with grandparents along with his wife and child. He's the only child living with them. He must have done a lot of work on the farm. Eula died young from TB, and I think her husband remarried and moved away.

Private emails had this:
Also thought you might like this. Grady got his mother's share of James Thomas's estate. Ok so Homer was found dead in a barn, said to of been hit in the head, my dad thought one of his sons killed him for money??? I have messaged a few times a Perry Post who grew up in Texarkana now living in Texas, he is a son or grandson of a sibling of Grady and Jack, maybe.
