Stephen Foster wrote many of the popular songs* in 19th-century America.  I didn't know it when we named our cat, but Stephen Foster wrote the music for an 1863 song called "Katy Bell."  You can listen to it, and if you're as interested as I was, even find the lyrics as well.
* - The most famous:  Oh! Susanna; Camptown Races; Old Folks at Home [Swanee River]; My Old Kentucky Home; Jeanie With the Light Brown Hair; Beautiful Dreamer.
