The earliest Roggerman we found so far is Charles John (1855-1941) who came from Rügen Island in the northern coast of Germany.
 Ralph Raymond Roggerman was a sailor on the Great Lakes when he married Adeline Getty in 1909.
Although the rest of his family used the name Roggerman, one of Charles' sons, George, chose to drop the second "r" and went by the name Roggeman.
Ervin "Rocky" Roggerman worked in Yellowstone National Park.
We don't know why the Roggermans and Gettys ended up in Monroe County, Michigan.
Addie (Getty) Roggerman, wife of Ralph Raymond Roggerman was killed in a car accident in 1929.
The Getty family originated in a small town in what is now Northern Ireland.
Some of the Getty family lived in the northeast section of Ridgeway Township in Lenawee County next door to Monroe County. Others made their way into Antrim County in northern Michigan.
