Hi,
i think that your great grand parents are mine, My granddad was one of 11 children his mother Margaret ( Moran ) i think died when he was young lad and one of the other siblings which was born also died, my grandad was born in 1901 and wasnt on the census of that year as it was taken before he was born but he is named on the 1911 one. both of my great grandparents are buried together in the grounds of st patricks church in drumshambo, i also managed to workout from the 1911 census one of his sisters was not listed and found she was listed at there mother sisters house. I visited Drumshambo a couple of years ago and found my mums cousin and family are still living there and found lots of history. I have copies of both census if your interested.
kind regards
Joanne x
