My 5th great-grandfather was William Swartz(not sure of spelling) born 1707 in Germany. In 1727 he immigrated through Philadelphia.His wife was Catherine. They had some children in PA and then moved to MD. Somewhere they changed the name to Black. Their son Christopher was my 4th great-grandfather. William died in 1771 and Catherine re-married. Christopher married Elizabeth Barlow. I have more if anyone needs it.
