My name is Roy C. Krohn, grandson of Roy S. Krohn, born in the Ubly,MI area around 1900. My father's name is George C. Krohn. I believe that Gilbert Krohn was my Great Grandfather and Henry would have been my Great-Great Grandfather. Most of our family line moved to the Gardendale area just North of Port Huron which is now considered Fort Gratiot, MI. My grandfather, Roy S. Krohn, had three brothers in which I remember. There was Cliff, Harvey, and John. There were also a numerous number of sisters. I am searching for my family history from Germany up to the present time as far back as I can collect.
