No doubt that's "priceless" = "very expensive", not "priceless" = "very funny"?
Clearly you're right - but this also applies to other names as well, surely? People complain about Caleb
, for instance, because they find it distasteful to give a child a name that means "dog" ... but people don't go through the wonderful Search function looking for a name that means "dog" in the first place; they like the biblical connection and/or the sound of the name. Probably the sound. Not many Philomenas, compared to Anthonys, and practically no Frideswides, though they've got perfectly respectable religious pedigrees.
