I'm researching my great grandfather and his father who were born in Cork. My gt gt grandfather was Charles O'Driscoll, born 1796 in Cork, married to Catherine and have 2 sons listed as Charles (1826) and Timothy (1829)who were both born in Bandon, nr. Cork City. They had relatives in Wales called Walsh so there could be a connection. I have them all in London in 1841 Census but cannot find them before that except for Timothy's birth.
