Hi !!!
I found that in Italy there is a rare name (but still used as in 2016 less than five babies were given this name) that is Brenno.
Brenno via Latin
Brennus could be the Italian form of three Celtic names:
Brennan,
Brendan and
Bran.
I was surprised in a positive way that it exist! Well..it is rare yes, but not extinct yet!
WDYTO it?
