My wife's great grandfather was supposed to have been a doctor and had a medical practice in Grand Haven, Ottawa Co., MI in the years after the Civil War. He served in the 111 Ohio Vol. Infantry but his CSR isn't a lot of help about his occupation. We know he died in Shelby, Oceana Co., MI in March 1911 and is buried in Mt. Hope Cemetery there. Is there someone visiting this forum who can varify his occupation/profession and confirm his medical practice in Grand Haven, MI?
