Judy is a name of Hebrew origin, derived from the Hebrew name Judith, which means 'woman of Judea.' It was popularized during the mid-20th century and remains a classic choice today.
The name Judy peaked in popularity during the late 1930s to early 1940s, with a significant spike in births in 1939 (36 births) and 1940 (43 births). However, it seems that by the mid-1970s, the name Judy was no longer as popular, with fewer than 15 births recorded each year from 1972 onwards.
