I put the death date into Findagrave and found a photo for his headstone, along with the name of his wife, Julia Cain, in Marion County, Kentucky. It looks like I will have to make another visit to the National Archives in DC to see Cain's pension file. This may be a stretch, but I wonder if this Cain is connected to my second-great-grandmother Mary Alice Cain Read and her brother Harl P. Cain.
Back to the 1860 US Census, Cain (age 26) is living in the household of Edmond and Honora Halloran, both of Ireland, and their children Ann and ten-month old Patrick. My guess is that Honora is the sister of Patrick, but I don't know if this is correct.
From looking in the Kentucky Marriage records, 1851-1900, Patrick Cain married Julia Lynch in Washington County, Kentucky on 16 June 1891. She had previously married Augustus Lynch in Marion County, Kentucky on 14 June 1874, her maiden name was Downey. Patrick and Julia appear in the 1900 and 1910 US Census in Lebanon, Marion County, Kentucky.
The couple are buried in Saint Augustine Church Cemetery in Lebanon, Marion County, Kentucky.
