Daniel Kelly & Mary Diver information

I am looking for information on my Great-Grandparents, both born in the Clonmany area. They were both born before most records were kept. I would like to find out more about their dates and places of birth as well as those of their parents and any other relatives.

Daniel J. Kelly was born in Annagh, either 1816 per his Boston Death Certificate or possibly Feb. 1822 per 1900 a Boston Census. He married Mary Diver (Dever) in 1857 in Clonmany, Donegal. Daniel died in 1906 in Boston, MA.

Daniel’s father was also named Daniel Kelly, possibly born 1802 in Annagh, Donegal. He died in1887 in Clonmany, Donegal .

His mother was Fannie (Margaret) Doherty. She was possibly born 1802 in Donegal, and she died in 1867

I have no confirmable information on Daniel’s siblings even though I do have the names of other Kellys from Annagh in about the same time frame. I also have names from the 1901 & 1911 Censuses.

Mary Diver (Dever) was born in 1841 (per her Boston Death Certificate) in Eightercluna, Urris, Clonmany Donegal. She married Daniel Kelly on 22 Feb. 1857 in Clonmany, she died 30 Dec. 1892 in Boston.

Mary’s father was William Diver, possibly 1808-1880. Her mother was Ellen Gibbons (Gubbin). I think that she died in 1892 in Letter, Clonmany, Donegal

Mary Diver’s Siblings from Family info were:
Ellen possibly born 1837 married Michael Doherty 
Hugh born 1840, I believe that he married Ellen Duffy in Boston, MA, he died in 1910 in Boston, MA 
John (Owen) possibly born 1853, he married Mary Doherty
Patrick possibly born 1849, he married Anne (Nancy) McCarron

Celia possibly born 1854,she married Edward McGonigle 
Quinton born 1860, he  married Ellen Doherty
Bridget born about 1859, she married James Mullen, shedied in 1910 in Boston, MA 
Philip possibly born 1862,  married Margaret Farren
