My great grandmother was Mary EGAN who died in 1896 in Lehigh County, PA and was born about 1856, in Ireland, I believe. My great-grandfather reported that she was from Chester County, PA. I find her listed in the census in Chester County only as a servant on a farm. I believe her to be the daughter of Daniel EGAN of nearby Newtown Square, Delaware County and believe that Daniel and his wife, Mary, arrived in Philadelphia in 1860. Does anyone have any information on these?
