I've come across this one for Italy: https://www.italianames.com/italian-last-names-maps https://www.italianames.com/italian-last-names-maps It has regional heat maps, but I prefer the one provided by surnamemap.eu It seems more granular and more comprehensive (my mother's maiden name is rare and it shows up on surnamemap.eu, but does not on the site that I linked to). I've actually used the surnamemap.eu site for maaaybe 10+ years. However, I don't know if it's updated, and if so, how frequently it's updated.
