Re: Nichodemus Legrand Hackworths- Second Wife Mattie?

I could be wrong on all this.
My ggg-grandfather Hiram Frank Wood married a Kate Hackworth (born April 3, 1889 in Hunt, TX) I believe Hiram Frank also married her sister Martha "Aunt Matt" Hackworth after Kate died. They had a son named Hiram Legrand. Supposedly they came to TX in a covered wagon. I found information of Nichodemus Legrand's first marrage to Thelow but none for Mattie.
any information would be greatly appreciated
