No relation but ...
Living in Francis Streeet, Dublin were:
Laurence Cribbin, 27, Butcher, born Kildare
Julia Cribbin, his mother, 56, born Kildare
sister Mary, 22, born Kildare
son Thomas 1, born Kildare
Wife Kate, 27, born Kildare
Therefore, Thomas must have been Julia's husband and Laurence's father.
They'd moved to Portarlington town in 1911, and had more children.
Lena (Helena on the 1911 census) Cribbin is living at Curryhills with her father Edward, aged 50, Mother Ellen 35, + sister Anne 11, and brothers Andrew 6 and Denis 4.

, there are lots of Cribbins/Cribbens, including some living at Curryhills. I imagine they're all related as lots of the same christian names keep cropping us.
