I'm interested in your line of the Haynes family. I was able to find some information on Gilbert Haynes for the other person looking (unfortunately, I don't think that I found anything more about his death.) I was working on the Haynes family because my GG grandmother was Mary Frances Haynes. She married Calvin A. Beard. She was the half first cousin of Gilbert Haynes (same grandfather-different grandmother.) Although my concentration for the last several months has been chipping at my Beard brick wall, when I saw the name Womack in your posting my ears perked up.
To try and make my way through the Beard brick wall, I've been researching the "collateral lines". I believe that several families intermarried over several generations and that the families of Mary Frances and Calvin knew each other before they got married. Calvin's maternal grandmother's first husband was a Womack.
Calvin and Mary Frances lived in Jasper County and their 3 children either lived there or close by in neighboring East Texas counties.
I have more information on Gilbert's ancestors if your interested.
