I can understand the truckloads of ladies in the Villages being named Judy... The demographics would have many born in the 1940s and Judy Garland was the darling of America. Many parents probably named daughters after her.
Is that it?
OK... but what about all the Lindas? They're all over the place too! Linda Darnell? Not THAT big.
Maybe I have too much time on my hands...
