Martin and Brigid Power of Callan Kilkenny

Hello there, I'm trying to complete my search on birth mother Eileen/Ellen and, her parents, probably Martin and Brigid, nee O'Connell. Brigid died in 1938 when Eileen was 3 years old. Martin remarried Catherine Gannon in 1939. I think that these people were farm labourers. I know that Eileen left for England when she was fifteen, maybe with other siblings? Can anyone help me to flesh out this story for me please? Eileen died in 2008.  I didn't know her as I was adopted. Thank you, Gerry
