Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
Men in this Regiment were recruited from Franklin County, Allegheny County, and Monroe County , and from the city of Philadelphia and Philadelphia County.
