Butler, John DOB c. 1880 Belfast area

[Mollyrose]

Hi, I am new to this so hope someone can help me!

I am trying to trace details of my grandfather. What I know so far:
He was born roughly 1880 in the Belfast area
He married Catherine O'Neill in Sacred Heart Church, Old Park Road, Belfast in approx. 1910.
He was killed in action 3 months before the birth of his youngest child (my mother).
He had 2 sisters (Sarah &  Mary)

Thanks for any info at all,
Jo
