Looking for Hand family members

I am looking for information about my Mums side of the family. My Mums maiden name was Hand, her fathers name was James, I know my grandad's family came from Annagassan, Mum said they were fishermen. My great grandfather Hand married Jane Matthews who died when my grandad was young, great grandad remarried and moved the family to Dublin.
Any information would be great.
Thanks in advance
Ria.
