You might look in Coleman County, Texas, where a large group of Sansoms moved to after leaving Gonzales. I know there was a Dr. Powell in McCullough County, Texas which is also where ther were Sansoms.
I will look in my McCullough County Historical book if you think this is a possibility.
Thanks so much for all of your help. Were the Sansoms, McAda's and Powells families in Texas very early? I met a friend of a descendant of Dr. Powell, and your e-mail has wrung a bell in my head. Do you know how the Sansoms, Powell, and McAdas were related to the Sansoms of very early San Augustine,Texas? There was a Rev. Sansom who was here very early, and for some reason I have a letter from him to his children back in Tenn. I have been trying to find the connection between him and the families in Gonzales.
