Hi! This is Sean's dad. The information I have is the Penndorf family may actually be Benndorf's or Bendorf's. Our side of the family came from the town of Posnick, Saxony. My father, Paul Richard Penndorf, emigrated in 1922, I believe. He came over with his mother, Ida, and father, Ernst, and his two sisters, Elfrieda and Getrude. The landed in New York City where they settled. My father married Marie Agnus Zimmerman, and they had three children. I am the oldest. My sister, Karen Knight nee Penndorf was born in 1947 and now resides with her husband and family in the Philadelphia, PA area. My brother, James Bruce Penndorf,was born in 1958. He now resides in Macon, GA with his wife and two childen. I had heard that there was a Penndorf family reunion in New York State but was never able to get more details than that. I would be interested in hearing any thing you can come up with. There was a Prof. Penndorf in the Boston area who had published the history of the Penndorf family back to the Middle Ages. I have a copy someplace and would be willing to post some information from it if you are interested.
