The grandparents bumped into somebody in the elevator at the hospital this weekend who mentioned that Pace also means “peace and harmony” in Italian (if you follow this link, click on the volume icon to hear it pronounced) as well as Middle English. We didn't know that but that's cool too.
As with the nickname “Peso”, I thought we might've ended up with another unexpected but fitting Mexican/Spanish connection since Italian and Spanish are such similar languages.
No such luck (although the Spanish meaning of Pace is very appropriate these days too! )
