CUNNINGHAM resort on Au Sable near Grayling

Looking for information and / or photos / clippings about a lodge or resort run near McMasters Bridge by Vernon Leroy CUNNINGHAM and his wife or mistress Delilah MARTINDALE from circa 1931 - 1961.Also involved were his brother Simon Luther CUNNINGHAM (a former butcher / meat inspector) and possibly a man named McCABE.Simon adopted the children of his 2nd wife, Ruth Gertrude WILDE who was the widow of Leo Glenn SHELTON.I would very much like to find CUNNINGHAM relatives or likenesses and stories about these folks.
