Looking for any information about my relatives in Gratiot County. My great-grandfather was Dr. Elmer Lucius Street, MD, who had an office in Wheeler approx. 1920-1930, and my great-great-grandfather was Donald McGregor, who owned land in Emerson Township, 1866-1880. Also can anyone tell me where in the county Emerson was/is? Doesn't show up on any maps...Thanks!
