Robin:
You are in, man, if you're related to Wm. Berryhill!
I'm the co-historian of the 43rd MS Infantry (along with the Hon. Scott Bell of the James P. Douglas SCV Camp in Tyler, TX).
Berryhill was a gallant and a dedicated Southern Patriot.
If you're descended from him, you are fully qualifiled to (1) join the SCV and, (2), be exceedingly proud of your glorious forebear!
Please email me privately if I can answer any questions about the 43rd MS -- the "Camel Regiment"! -- Jim Huffman, 43rd MS
