Thanks you for your reply- I have since found out that this JOhn SInger that went on to run a tanning business in Philadelphia came from Capser Singer Jr. and Casper Singer Sr. Casper Singer Sr. was an early landowner in Philadelphia and later lived in Lancaster CO. He is the father of Casper Jr., who is the father of John Singer - who had a daughter that was the mother of John Singer Sargeant. I was looking into the Musser link as our Singer DNA matches a Musser and we have been trying to figure out where the paths crossed. I found the Singer married to a Musser connection- in Lancaster co. I have not been able to prove out DNA link to Casper's family- but we did have two families living in Lancaster Co. (now Dauphin CO.) that might have come into contact with the Musser family living there.
