George's birth certificate, 1926, and his siblings might be obtainable, from the Irish GRO in Roscommon. I don't know if the restriction applies to availability or just being online. Someone on the Wexford board or general Irish board will know. The certificates would tell you for sure if those are the right parents, the Irish certs. include the mother's maiden name.
