Mr. Hodges, I think Joeseph Denbo and his wife Mary are the parents of my great-great grandfather John. My great-great grandfather was John Denbo from Crossville Illinois (?-1952), but was born around Mt.Vernon Indiana, and was married to Estell Denbo. My grandfather is Marion Denbo also of Crossville (1914-1986). My great-aunt is Claire Elizabeth Denbo Martin (1907-1995). Their brothers were Horace Denbo, and Warren Denbo (died as an infant). I hope you find this to be useful information.
