Karen,
I have been doing more research on the Eiberger's I am writing to a Catholic church in Chicago where I do know that some of my Eiberger's worshipped. I had been told from a family member from the other side of the family about this church. I also found that my own great grandmother had gone by a middle name or maybe her first name meaning that she used both names Frances and Marie.
I have been discovering many things, I was in touch with Ethlyn Eiberger who was married to George who was a cousin of ours. She also gave in sight on where else to look for info. Where are you located, so I can try to match some data for you.
