Torian is not a traditionally British first name. The British Name Generator would not produce a surname to match it directly as it's not in its database of common British names. To get a suitable surname, you would need to provide additional parameters to guide the generator towards a compatible style. For example:

• Region: Specifying a region (e.g., England, Scotland, Wales) will influence the surname suggestions. A name like Torian might feel more at home with a surname from a specific region, perhaps one with a less common or more modern feel.

• Style: Choosing a style (e.g., traditional, modern, quirky) will help narrow down the options. If Torian is intended to sound modern, a modern surname would be appropriate. If it's meant to evoke a sense of history, a more traditional surname would be better.

• Age Group: The age group can influence the choice of surname. A younger-sounding first name might pair better with a more modern surname, while an older-sounding name might suit a more traditional surname.
