Hi, Vicky.

The main question I have about the DC is the burial place. Although the trascribed Death Certificate info has his place of residence as Grand Prairie, Dallas County, it says he was buried in "Fort Worth".

Fort Worth is in Tarrant County; a part of Grand Prarie is in Tarrant County.
Is this an error?

I love this site by A. Wheatley.
