He's not mine (I don't think) but I happened to find a Horace Young who died in Stanstead, Aug 8 1874, aged 45 years in a book called "Stanstead County Vital Statistics January 1861 to December 1875" while I was at Salt Lake City, UT last year.
I'm tracking the Isaac Jr. Young who died in Essex, IA, 3 Oct 1874. He was b. in Canada (probably Stanstead) 18 Apr 1824.
