Hello Patricia;
I looked in the NSDAR Patriot Index and did not located either Frederick or Henry Boyer. That doesnt mean he didnt fight, it means that no one has joined the NSDAR Membership using his lineage.
Some places you can visit on the internet in regards to PA military in the revolutionary war. I believe most soliders that were from PA fought at Valley Forge, I am not sure of this statement but at the Valley Forge Muster Roll website, it has a database that lists all the men who were encamped with General Washington during the winter time encampment. The URL is
http://valleyforgemusterroll.org I checked there is a Fredrick Boyer listed there. Henry wasnt listed.
Another place to view is the PA Historical and Museum Commission - PA Digital Achives.
http://www.digitalarchives.state.pa.us/ It has Revolutionary War Abstract Card File
Hope this helps and if we can help you again, please feel free to contact us.
Warmly,
