Latin Names as found in RC Church Registers.


When people search a register or database, they will be searching for example, for the first name William rather than the Latin equivalent Gulielmus, etc.

Note that Latin names were not used in every-day speech. They were only used in the formal written form usually in Church Registers.

The every day speech form (spoken in the table below) was essentially the same as we use it today. The Dorothea Doherty of old didnt shout "Bartolomaeus... get in here for your dinner!"
