Who is Barnaby?

Every time I use Gemini to make some sort of a story (books, movies, video games, etc.) the name “Barnaby” pops up.
A few days ago, I asked Gemini to write a story. For some reason, TWO characters had the name Barnaby. Out of the hundreds of millions of names out there, Gemini couldn’t think of anything else but Barnaby!
Just now, just to confirm, I asked Gemini to come up with a mascot horror video game plot. Unsurprisingly, the name of the game was Barnaby’s Transit Town, with the main character “Barnaby the Conductor”.
And when I asked it to tell me a random name for a movie character, The boys names were Arthur, Leo, and Barnaby.

Can someone please tell me why Gemini is obsessed with the name Barnaby?
