Trying to locate information on Leo Hinckley. Leo was listed in my g-grandfathers (Harvey Munger)obituary as a nephew.Harvey died in 1943 at the age of 81.Leo must have been born ca. 1880-1910.I do not know if Leo was the son of a sister, or his first wife (Name unknown). Any information would be greatly appreciated. Harvey had two sons born in Detroit, Harmon and John.1892/94.
