My great, great grandfather was Albert Field Mansell. His son was Richard Aaron Mansell, then my grandmother Jessie J. Mansell who married Roy Leland Beckendorff, Sr., then my father Milton Richard Beckendorff.
To answer your original question, I believe the Albert Field Mansell was buried at Field's Store Cemetary in Waller County, TX. I would have to check further to swear to it, but my chart says he is buried at Waller County, and his son, Richard Aaron was buried at Field's Store, as were many other Mansell's. A few were buried at Garrett Cemetary.
