I am very much interested in your Richtig line.. My great grandfather, Stephan Pfeifer's mother was Elizabeth Richtig who married Anton Pfeifer.. When he came to US in 1893/ he landed in Iron Mountain, MI.. The family said he has a sister, Agnes but we have not found her family.. Old family members remember seeing her when they were young but I have not found her or her family..I have traced the family to Kaerton, Austria with no definate town except Feistritz and St. Jacob. If you have any information, I sure would appreciate it..
