My great-great grandparents were Samuel H. Rial and Margaret Grove Rial. She is buried in Homewood Cemetery in Squirrel Hill, near Pittsburgh (1820-1904). The same tombstone lists an "In Memoriam" to Samuel H. Rial (1820-1871). He was born in New Jersey and moved to Washington County, PA. I believe he may be part of the Isaac Rial line but have never been able to find his parents or any other connection. Samuel and Margaret moved to Pittsburgh in 1866 and he ran the Merchants Hotel. She out-lived him by 30 years. They had seven children -- Mary E., AmandaF., Isabella (Bella) C., James G., John H., Emma C., and my great-grandmother Annie Cannon Rial. Would appreciate connecting with anyone from this line, or anyone who can provide further info on Samuel or Margaret's ancestry; I'm stuck. Thank you.
