I can tell you what I do, which MIGHT be of use.
My first banjo piece I named for my wife, Dorris. The name was "Little Dorrie".
Second I named for myself, sort of: "Pop's Progress." Third, in honor of my son-in-law, who is known far and wide as "Dancin' Bob".
When my daughter was a baby she was the kickingest baby you've ever seen--not just bicycle-pedaling, but kick-kick-kick! I had just read a novel which referred to a historical Indian chief, Kicking Bird, so she became known around our house as "Kickin' Bird,", and so the next tune was "Kickin' Bird".
I have another tune in the works, and it may have a family reference name or maybe a reference to our street name, which is Crow's Nest Drive.
In any case, there are lots of them right there in your own experience and environs, and they are less likely than many to be something that's been used.
