Searching for Hickeys and McGraths

I am not sure if my Hickey/McGrath relatives are from Knockainy, however, after much research in Griffiths Valuation and the 1901 and 1911 census, I have determined this is a possibility as there appears to be many Hickeys and McGraths in this area. I would appreciate any help you can give me. The following is what I know of my family:

James Hickey - born about 1790 - 1799, Ireland,  died in Boston, MA at 20 Prince Street in 1879, came to USA about 1847. Parents Thomas and Ellen Hickey.

He married Ellen McGrath - born about 1807,in Ireland,  died in Boston, MA at 20 Prince Street in 1884. Parents Daniel and Bridget McGraph/McGrath.

Children: Hannah Hickey born about 1828 in Ireland. Married a Richard Hunt. They had 10 children born in MA - 3 lived.

                  Margaret Hickey, born Ireland, about 1830        

                  Ellen Hickey, born about 1833, married Dennis Driscoll in 1861, her 2nd marriage.

                  Catherine Hickey, born Ireland about 1834, married my great, grandfather Jeremiah McCarthy, in Boston,MA

                                                   January 26, 1864, they had 4 girls and 1 boy. Their daughter, Catherine McCarthy, my   

                                                  grandmother,  married Peter Maloney. Their only child, Richard Maloney, was my father.

                   Julia Hickey, born about 1838 in Ireland.

                   Bridget Hickey, born about 1839 in Ireland. Married a Daniel Sullivan in 1857 in Boston.

                   William Hickey, born in 1854 in Boston, MA, never married.

Many thanks again.
