Wray (Ray) and Kee Families

Trying to find family informaiton in Ireland for John and Mary (nee Long) Wray.   I have been trying to research them for quite some time but keep hitting brick walls.  Any help would be most appreciated.  One child married Robert Kee but I do not have any information about them either except I found them in the census but not all living together.

John (my ggrandfather) was born about May 1820 in Ireland.  He died abt Dec 1911 in Ireland.  He was listed in the 1901 census as John Ray.  In the 1911 census the last name was Wray.  Not sure exactly because the 6 children who emigrated to America changed the spelling to Ray.   I would love to know their actual name.

John married Mary Anne Long, daughter of Alexander Long on 29 Dec 1848 in Donaghmore Donegal, Ireland, Presbyterian Meeting House.  She was born abt 1831 in Ireland and died after 1911.  6 of their children stayed in Ireland and 6 came to America.  John and Mary lived in Carricknamana, Killygordon and also I have a note that says Ballybofey.

Their children -

1. Nellie L. (or Ellen) born 1852 Ireland and died in 1935 in Connecticut USA.  Not sure if her name is Nellie or Ellen.  She lived in New York City for a while before moving to Connecticut to live with her sister, Margaret.  Nellie never married.
