If anyone has any information on his parents (either biological or foster), please contact me. I know he married Katherine Karst. According to his death certificate, his father was Antony, but his mother was unknown to the one filling out the certificate (Katherine). I found a picture that had the Grimms, Frank's foster parents written on it. I have found S A and Margaret Grim in censuses in Missouri with wards in their household, so this would make sense. Katherine and Frank were married in Missouri, but Frank was born in Ohio (possibly Wauseon, Fulton). Anything would help. If you came here looking for info, feel free to ask!
