Mary Katherine Vodde, on a US census, listed she was born in Hamburg, Germany. When she marred Frank Ostendorf, in Ohio, they were married at St. Peter's German Evangelical Church in Cincinnati OH. That is about all I have to offer so far on this branch in my tree as far as locations and church affiliations as I am related to them through her marriage to my great-grandfather - but there were some Ostendorfs listed in Ripley County IN which, if they were relatives of Frank's, may help lead to how Mary Katherine and Frank Ostendorf may have managed to meet.
