My interest is that Tom might be connected with the Geerin/Geren/Geurin/Guerin families in Bradley Co., TN; I have a missing Tom but he was born in 1840's and fought with the 10th Texas in Georgia 1864, last time he was documented. Is the Denton Co. Tom Gerren related to those in Bradley Co., TN and Jackson Co., Alabama--that's my interest.
I have the death certificate image for his granddaughter. His wife's body was supposedly moved from Denton to be placed beside her husband after he died October 1912 in Fort Worth--where there is no death certificate for him.
There are some articles about him in the Denton and Dallas papers, one written by a writer with a grudge, who called Tom the bully of the town, supposedly met his match by a negro who stole Tom's horse and gun and escaped, later Tom was allegedly reported as pushing a fruit/vegetable cart in a small town near Houston and also claiming he had no living kin, but that doesn't match the articles of his working as an agent for the Santa Fe.
The Denton article of 1909 has Tom Jr. visiting Denton from South McAlester, Oklahoma--this is not Robert's son Thomas or a member of the Geren family in Grayson Co.--this Tom Jr. is related to deputy marshal Tom Gerren.
