U names

U is also a letter which isn't very popular for names. One female name that was fairly popular in bygone days, beginning with U, was Ursula. It means "she bear" and was the name of a medieval saint. Una is an Irish name, meaning lamb... and was also quite popular in the past. Another rarely used name is Unity. It means oneness, but it is not popular, especially as it was the name of the fascist supporter and society girl, Unity Mitford.
