WAGNER roots in Philadelphia

I'm searching for my WAGNER ancestors in Philadelphia, The earliest I have is Adam WAGNER, b. 1781, d. 1836 in Schuylkill Co., PA, m. 17 March 1807 to Maria BILGER, b. 13 October 1786, d. 17 July 1853. Adam was a weaver and farmer and lived in Montgomery & Schuylkill Cos. I've found a record of a brother, Frederick, who lived in the Northern Liberties section of Philadelphia, but whose estate was settled in Montgomery Co. instead of Philadelphia. I don't know if he died in Montgomery Co., or if it was settled here because Adam lived here at the time. There were a lot of WAGNERs in Philadelphia in the late 1700s which makes finding them difficult. Adam attended the Lutheran church in Schuylkill Co., so would assume he did the same in Montgomery and/or Philadelphia Cos.
