Hi Kate
I found on IGI (submitted though, so will need checking)
Abraham McGill b1837 bap St James church, Whitehaven
Father - Andrew McGill
Mother - Esther Montieth (Esther's father is James Montieth)
Andrew and Esther married in 1835 at St James church, Whitehaven
It also says that Abraham married Maria Hilton in 1859 at Everton, Lancs
But this Abraham died in 1874.
It seems there were two of them living in Whitehaven, born a year or two apart, but one born in Whitehaven and one born in Ireland.
Not much help, but now you have two of them
