Does Dominic have a last name in Caged Flower?

Answer 1

In Caged Flower, Dominic tells Violet in the Repository that he knows very little about his birth, and that he doesn't even know if he has a last name. This shocks Violet, who finds the idea of not having a surname "incomprehensible." But as of the end of the book, we still have no answer to this question.

Without providing a spoiler, details about Dominic's early childhood and how he came to be with the Friendship are revealed in Book Two of the series. The answer to the question is found there, along with a few surprises.
