I can confirm that the Orean B. WILSON mentioned in your message is indeed Orean Bennival WILSON, son of Delbert L. and Bessie H. (Guise) WILSON. He was born in near Culver in Marshall County, IN on 6/17/1918 and died in Indianapolis, Marion County, IN on 6/2/1974. His paternal grandparents were Leonard and Mary Ellen (Ruggles) WILSON and his maternal grandparents were Bennival and Emma (Calhoun) GUISE.
Orean's obituary in the Bluffton newspaper was incorrect regarding his burial location. He is actually buried next to his parents in the Poplar Grove Cemetery which is located just east of Culver, IN.
I am distantly related to Orean - 2nd cousin, twice removed. Unfortunately, I do not know any of his immediate family. The information that I have on the Wilson family comes from my genealogy research.
Orean was married at least twice. First in 1941 to Helen L. NEWMAN and second in 1967 to Barbara BAUBLET. His obituary from 1974 mentions 5 surviving children: Patty DICKHOFFER of Wabash, IN Sharon STUCKY of Lagro, IN and Mary, Tonya, and David WILSON, all of Bluffton, IN. The first 2 children are from his 1st marriage and the last 3 from his 2nd marriage. I am unaware of the current whereabouts of his wife Barbara or any of his children.
From my research I do know that one of Orean's brothers, Charles Cecil WILSON, died in February of 2004. I located an obituary for Charles and it mentioned that he had 3 surviving siblings (as of 2/2004): 2 sisters, Opal NELLANS and Louise PESSLEY, both of Warsaw, IN and one brother, Mike WILSON of LaGrange, IN.
