Or how is it with Patience? Would she be up for a forced marriage perhaps? That can be up for discussion though.
I'm currently working on a oneshot between Nathaniel and his father, James Harold Piper. James tells Nathaniel that if he hasn't found a bride by his 31st birthday then James is going to find one for him, and that he is expecting a son within the next year.
Sound anything appealing to you? Either, the forced wife, or, perhaps one of Nathaniel's choice, though that cannot give him a son so his father forces them apart?
