Final answer:
Ms. Borden's first name is Elizabeth, also known as Bess, and the text does not provide Mr. Borden's first name.
Step-by-step explanation:
The first names of Mr. & Ms. Borden, referred to in the text, are not explicitly stated. However, we know the female character is often called Bess, and later in the text, we discover her full name is Elizabeth Erne; hence, Ms. Borden's first name is Elizabeth. The text does not provide the first name of Mr. Borden; it is Venters who discovers the girl's given name. The characters likely come from a piece of literature where their relationship and identities unfold within the story's narrative structure.
