Katresa is of Hebrew origin and means 'pure'. It's a unique, elegant choice for a girl's name.
"Katresa had a notable start with seven births in its first year (1973), followed by consistent popularity with six births each in the next two years (1974 and 1975). After a gap of several years, it resurged with five births in 1981. Overall, Katresa has been chosen for 24 newborns."
