Sorry for the delay in answering your E-mail of Feb. 10. I'm not sure who Joseph Seabeck was. My grandfather's name was originally Frank Pogrzeba but I've never been able to find when and where it was changed. He did live in the Peru/Princeton/ Spring Valley area and was married to Mary Bonk. Her family is buried in Northeim, Wis.
George and Catherine Seabeck lived in Spring Valley and are buried there in SSs. Peter & Paul Cemetery. George was my grandfather's oldest son. The name is Seaback on the headstone.
