I have included the two Civil Parishes, Kilcolman (Costello Barony)(B) and Castlemore (A) that were transferred to County Roscommon in 1898.. There is a section on these Civil Parishes in both the County Mayo Townlands and Parish Characteristics sections of this website.
I have used Brian Mitchell's Book "A New Genealogical Atlas of Ireland" as a reference to confirm the Civil Parishes to be included in this County Mayo Civil Parish Map.
