This entry appeared in the Clinton Republican in Wilmington, Ohio on January 5, 1887:
Jeremiah (Jerry) Coakley died Friday, December 31, 1886, at almost 87 years of age. He was born in Ireland and was of the Catholic faith. He was buried in Sugar Grove Cemetery.
In the 1880 census, Jerry was living with his wife Mary and their son Timothy and his family in Clinton County, Ohio.
According to FindAGrave, Jerry's wife Mary Ryan Coakley died almost a year later in December, 1887. There is a nice picture of their gravestone on FindAGrave with the following inscription:
Natives of County Cork Ireland.
Merciful God grant unto them eternal rest and may the perpetual light shine upon them,
The 1915 history of Clinton County, Ohio by Albert J. Brown states that Jerry Coakley was one of the attendees at the first Catholic mass in Clinton County in August 1852, along with Patrick Creedan. In 1864, Jerry was one of the organizers behind the effort to build a Catholic Church in Clinton County. I suspect there might be a link between Patrick Creedan's first wife Mary Coakley and Jerry's family, but haven't found anything definite yet.
Updating to add that I found a second obituary with more information on Jerry in the Clinton County Democrat. The second obituary is posted here.
