That's why we always just say Queen Elizabeth, Prince William, Prince Henry, etc. They don't. However, you sort of could substitute their House name. So, currently they are of House Windsor (after quick googling). So, Elizabeth Windsor isn't too bad. So, we could follow suit with Regina as Regina of House Mills, Regina Mills, or Queen Regina of the Enchanted Forest (that was what David was referred under, despite the EF being a region).

It's sort of like Game of Thrones. House Lannister, House Stark, and they could easily be "Of Winterfell" or "Of the North", but they usually go by "Of House Stark" or Arya Stark for casual conversation amongst fans.

The issue is the variability in Once.
