I don't know if this information pertains to what you are looking for. The dates of birth do not match with what I have, but the other similarities are so close, i thought I would pass it on. I have TWO brothers John and Henry, whose father is reported to be named Henry. John was born in 1779 and died in 1856. He was married to Priscilla Hemperly in 1828. The other brother Henry was born 1801 and died in 1869. He was married to Mary Hemperly in 1832. Both men were from PA.
