Thomas and Tirzah's youngest son, William McWillie Williamson (my 3rd Great Grandfather) was born about 1844 in Shreveport, LA. He married Mary Ellen "Mollie" Reese in 1862 in Brazoria, Texas. She supposedly divorced him in 1874; Mollie remarried, had one son with her 2nd husband and died in 1878. After the 1870 census (he was living with Thomas Taylor, Mollie and their children in Refugio, Texas at that time), I can find no records of William McWillie Williamson - who was supposedly a doctor. Does anyone know what happened to him? Did he move back to Shreveport?
