As a followup to my previous post if you haven't already, I would start my research with Griffith's Valuation. It was taken in Galway in 1855 and listed the head of every household. The Heanys are predominate in Ballynakill Parish in Connemeara where there are 45 of them. In the 1901 Census the name was spelled Heanue and there were 28 Heanue's in Renvyle which encompasses part of Ballynakill Parish. Unfortunately the Catholic Church records for Ballynakill do not begin until 1869 so they won't help for earlier dates. You can take a look at the Griffith's at this website. http://members.cox.net/hayes1966/griffiths.htm Dutch O'Connell
