Bunion, of Latin origin, means 'swollen' or 'enlarged.' This name is uncommon but notable for its association with the medical condition it shares a name with. It's often used as a metaphorical reference to something that has grown large or out of proportion.
"Bunion saw a total of 16 babies born over these three years, with peaks of 6 births in 1924 and slight drops to 5 births in both 1917 and 1933."
