Griffith's Valuation record question

It’s an agnomen or nickname to distinguish him from the other James O’Connor living nearby. Og/Ogue means “little”.

Thanks Elwyn! That's helpful to know the meaning of the word "ogue".

Actually, the Irish word óg, sometimes anglicized as "ogue", means "young", but it was used in the way Elwyn indicated.  In rural places, there were often people with the same name, so agnomens were used to distinguish between or among them.  The addition of óg usually refers to someone who was younger.  It might sometimes used with respect to size, but the word beag (often anglicized as "beg"), which means "small", would be more common.  Just to make things nice and confusing, though, beag could also be used to indicate a younger person.  Other things, like hair color, were also used.  The agnomen rua, meaning "red-haired", was quite common, and often anglicized as "roe", and dubh ("black" or "dark") could be used to refer to a person with dark hair.

Thanks Kevin! I always love reading your explanations of word origins!

If you are interested in the word Ogue in action, there’s quite a famous Irish traditional song called “Eileen Og” (little Eileen). Written by Percy French, about 100 years ago. Performed here by Cathy Jordan & Eleanor Shanley.
