"Tristan" now feminine given name

[sagehen]

John was certainly, mid-century, the most common boy's given name, it was
nearly always nicknamed "Jack."  I can't remember ever knowing a John who
wasn't Jack from the '30s to the '70s.  This might have been at least
partly because "john" was also the most common designation for the toilet.
Shortening and nicknaming seems to be less common now than fifty years ago.
Perhaps due to more parental management of kids' lives.
