Names as spelled in Irish Catholic Registers

Part 2

Irish Catholic Parish records were either written in English or Latin never  in Gaelic Irish.

The surname retains the English spelling  or a phonetic variation – the same surname can be spelled differently in various set of records. It was written down as it sounded.  

Many Priests were also not fully conversant in Latin.
