Hi Michele~
If you have not received any information about your Theophilus Armentrout, you might want to be in touch with Mr. Scott Harris at the New Market Battlefield State Historic Park, New Market, Virginia. Scott is the Director there. His ancestry contains the name Armentrout. He was originally from Staunton.

His email was and may still be: nmshh@shentel.net
540-740-3101 (maybe)

I have not been in touch with him for quite awhile but feel free to use my name.

Good Luck.
Dave
