I wanted to hear more about the woman whom Snell apparently courted and proposed marriage to on her return to England—it's mentioned (again without any commentary on whether this might be considered immoral) and then never comes up again.

I don't remember much discussion of her specifically in Jen Manion's Female Husbands: A Trans History (2021), but the book does talk about women who married female husbands—there's an entire chapter titled "The Wives"—and it's neat stuff.
