Alison, you'll have to be a gambler to go farther on this information. I checked the Griffith's index on failteromhat.com to see where Pages were most common in Connaught, found the majority in Ballynakill parish in Galway and Kilkeevin parish in Roscommon. Ballynakill records have been filmed back only to 1869, too late for you, but Kilkeevin records go back to 1804. You might ask the Roscommon Heritage Center if they have baptisms for Joseph, Patrick, or any other children of Christopher and Mary Page from 1820 to 1850. (Joseph apparently came during the Famine, and ships' records from that time are quite scanty. You might read Paddy's Lament or Galway Bay to get a sense of what they went through.) Good luck! Diane
