Good work Jim. I believe these children are the sons of Johan Philip and Barbara Straub. Philip and Barbara had a daughter, Catharina Elisabeth b. 3-1-1761 who was baptised in 1761 at the Lehigh Lutheran Church in Lower Macungie Twp, Lehigh County. Philip is taxed in Brunswick Twp, Schuylkill County, Pa in 1778. He is not on the tax list for 1779. He may have moved to Mifflin County at this time. Mifflin County is on the west side of Union and Snyder Counties.
