BLANEY, Henry c.1850 Cullybackey, Antrim

Here is what I know that I got from my late Aunt years ago and thank God I saved.My great grandfather name was Henry Blaney, his wife was Alice (possibly O'Neill).Henry was from Lisnahunshin, Cullybackey, Antrim.Henry she thinks died in Ireland, and Alice migrated to the USA, Boston, c. 1885-90 with her 10 children.She must have been an amazing woman!The Children names are:

Pat, Tom, (Daniel, my grandfather), John, Joe, Neil or Neal, William, Henry another that "went out West as a lad" that she could not remember his name or fate, and Mary.Nine boys and one girl.There could be more if an elder male stayed in Ireland on the family land or died as children before she left?
I Have some dates of birth and deaths on my granduncles and g grandmother.Looking for info. on g grandfather, Henry and his siblings, parents, and relatives in Ireland.
