Looking for Bennie M Hogg of Blackfoot Texas Palestine TX

I have been told all my life that my great grandmother's father was the brother to Gov. Stephen Hogg. I've been doing some research and have not found the link. If anyone can help please let me know. She was Bennie May Hogg B:6Mar1901 D:3Feb1988. She was married to Johnnie Ward. I believe her father's name is George Washington Hogg. B:16 Feb 1858 and D:30 Jul 1921. He was married to Annie B Wood. Don't know if that is correct though. I'm just wondering if there is any link at all to Gov. Hogg.
