I can only give you an educated guess. I looked at all the Pattersons, and found no Kevin.I did however, find 'New unmarked grave' in a Patterson plot.Here it is for your review:
MILTON TWP CROWN HILL STERLING CEMETERY PATTERSON Russell S. 1896-1913 Jessie M. 1903- Iona M. 1918- Donald T. 1928-1929 Albert 1888-1951 Alma 1896-1957 An new unmarked grave
If you would, please let me know what you think.Also, a big thank you for the ladies of the historical society for making note of such things. One other suggestion:Wayne Co Library holds an obituary index for these later years.I found my g grandmother's obit indexed for 1949 and was a breeze to find on microfilm.Maybe this could confirm it?
