Chasing Leonards

I'd sent off for the death record from the Cheboygan Co. MI library of a John Leonard in hopes that this would be THE John Leonard who was an Uncle of Thomas H. Leonard(Jim's Direct line) & living in Thomas H.'s household in the 1900 census. You can read my earlier post here. I don't want to go down the wrong road in this research but the age and location is certainly right on the money for it to be his Uncle. From the Death Info I learned that this John Leonard was a widowed farmer and was the son of Hugh Leonard & Dorothy Downey. This doesn't tell me for certain that this John Leonard is the one I'm looking for as I don't know for certain who Thomas H. Leonards parents were. It is progress though in that I can see if there is a trail from the Hugh Leonard & Dorothy Downey that might lead to Thomas H. Leonard's Dad.
