I've been tracing my family's migration from an ORNBAUM ancestor b. PA 1757. After serving in the PA militia during the Revolution, he moved to MD and then VA. His children and grandchildren moved to IN, MO, TX, IA,
and CA. Common spellings of the surname include Ornbaum, Ornbaun, Ornburn, and Orenbaum. I have reason to believe that the IA branch may have settled in Mahaska co. and possibly founded the town of Ornbaum. I am hoping you might be able to point me to sources that could tell me more about this town and the families who founded it. Thank you for your help.
