Hi! I am also looking for PA Rosch. I have found Catherine and Elizabeth Rosch {twins} in Bucks Co,PA born in 1881. Their parents were Henry Rosch and Christine. I have found a record of their baptism at the Trinity Union Lutheran and Reformed Church. I am trying to link this Catherine to Andrew Wirt. They were my 4/th gr.grandparents. They went onto Botetourt Co.,VA in the late 1700's. Do you think we connect?
