Not sure if you will see this but my husband and I live in Nester Township, Roscommon County. His great-grandfather and grandmother moved here in the late 1910s and we live where their home was. Nolan ROAD is only a couple miles from us so the fruit farm may have been along there and my husband also remembers a huge orchard a few miles north of us but it's overgrown with pine trees now.
Have you found anymore information about your ancestors? There was a schoolhouse a mile from here and one up the road - both gone though - and there is a small house that used to be a store about four miles from here that MAY have been the one your great-grandfather operated.
I looked up the 1910 census and we recognized names on it because some of the descendants still live in the area and my husband has a general idea of where they lived. If you would like pictures of the area, please let me know and I'll be happy to take some when the weather gets nicer.
