Is the title and cypher of a monarch modified if the Queen has the same name as her predecessing king?
In the United Kingdom, there exists a couple main signifiers for the monarch. The first is the title, chosen from a slate of first names. The second is the cypher, written like "E II R" surmounted by a crown for the late Queen Elizabeth II. This signifies "Elizabeth II Regina".
I was wondering how the title and cypher change for a King who has the same name as his heir apparent first born daughter. Consider the following scenario:
- King Wallace I reigns over the United Kingdom and other dominions.
- King Wallace's oldest daughter is also named Wallace.
- King Wallace dies, thus his daughter Wallace immediately ascends the throne and decides to take the name Wallace as well.
If #3 happens...how is the monarch's title and cypher affected?
Is it "Queen Wallace II" and "W II R" respectively? Or is it "Queen Wallace I" with a cypher of "W I R"?
