I have this name in some of my Frownfelter family history and I thought this name might mean something to someone from the Baldy family. I will copy the paragraph that mentions his name from my text.
"Nothing is known of Henry's childhood.We know that he was old enough to serve in the Revolutionary War. Pvt. Henry Frownfelter and Pvt. Felix Frownfelter were both in Captian Scheffer's Company of the First Battalion of Berks County militia on 20 January 1777 at Newton, Bucks Co PA.Evidently Henry's brother Felix did not serve with him in 1780 for only Henry was listed as serving on 8 September 1780 in Captian Baldy's Company of the Sixth Battalion of Berks County Militia.(Pages 158, 159 and 235 of Vol V 6th Series, Pennsylvania Archives.)
I thought this might be some information someone in the family could use.
