County Mayo Civil Parish Townlands And The Catholic Churches Associated With Them
I have included two Civil Parishes (kilcolman, Costello Barony and Castlemore, Costello Barony) that were in County Mayo when the Griffith's Valuation was conducted but later transferred to County Roscommon in 1898.
I used the late John Broderick's amazing website "The IreAtlas Townland Database" to identify the Townlands in each Civil Parish and then confirmed them after analysis in the Griffith's Valuation on the Ask About Ireland Website.
