I checked the google search engine and got a new website for the Orwigsburg(PA) Historical Society.It is: www.museumsusa.org/data/museums/PA/34611.htm However, there doesn't appear to be an email link from this site, so probably it's best to call Jennifer Frantz-Bowen at (717) 366-8713. She can give you information on the Orwig information that's archived at the Historical Society. My husband and I hope to visit Orwigsburg this coming summer as we have no direct knowledge of what the musem now has in its collections. When we were last there, there was no museum.
At some point, I'll post a descendants' chart for our branch of the Orwig family.
