Magdalen Kuhn was the eldest daughter of MIchael,Jr. and Eva Kuhn/Khuen of Philadelphia, Ruscomb Manor and Hereford, Bally, PA. Michael,Jr and Eva arrived in Philly in 1753 on the ship Beulah. Probably from Switzerland.
According to my records. Willliam and Magdalen (Mary Margaret) had 4 boys(William Peter, Lawrence, Augustine and Charles) who all died with in 3 to 4 months after they were born and are buried in the church yard at Bally.
Is this the family that you are looking for?
