ah, i see!
i do think the connotations of Mason and Xavier are more a West Coast thing, tbh, and perhaps a person from the East or the Northern Isles might not be as finely attuned to it.
i'm not sure, though, because my experience of the East Coast is somewhat limited.
it would not occur to me, however, to call my son an 'occupational' name or surname as forename simply because it is an American trend i don't much care for at all.
there are literally thousands of Tanners, Taylors, Masons and the like there. And tens of thousands of Jacksons, McFarlanes, McKenzies, Sawyers and the like.
these trends are at least a decade old there and i see they are crossing the pond with increasing frequency.
