But Cheryl and Cherry don't have the same initial sound. Cheryl has /sh/ as in shop while Cherry has /ch/ as in church. Cheryl was a very common name in my peer group (I was born in the 1960s), and while some Cheryls were called "Sherry," there was never any confusion with Cherry nor was Cherry used as a nickname for any of them. In fact, I've never known a Cherry.
