In the 1870 Hiseville, KY Census-Edwin is the older brother of Thomas Luther-father of Hugh M. In the 1880 Hiseville Census both are listed on the same page-Item 22. Their parents were Alexander M. McCandless & Frances Brockman, they had 12 children-8 males & 4 females.
I was able to find in the 1930 Falls Co Census a listing for a Dave Deeming, occupation-Undertaker by using the old census search. I will need to make some more inquires or a trip to Falls Co.
