Germanic. Interesting: a few years ago, out of interest, we underwent DNA testing. Mine, as expected, is Celtic (Scottish Highlands, Northern Ireland, Somerset, Devon, Cornwall) with a good measure of Viking. Mario’s is only 7% Italian. The rest: mainly Celtic, with a touch of Viking. The Celts, originally a central Germanic tribe, spread to Britain, and also occupied Friuli for the better part of a millennia. Our children remarked that this is rather creepy😂.
