Nicola here, talking slightly tongue-in-cheek about a certain trope in fiction, that of birth order. The concept of the “heir and the spare” is something that has been discussed quite a lot lately and it’s a theme that those of us who read historical romance are very familiar with. The noble family is desperate to have an heir (usually male, since women can’t inherit the majority of British titles) and that person will be expected to carry on the traditions of the family, inherit the title and any entailed fortune that goes with it. They will be in line to take the responsibility for the crumbling stately pile and if it really is crumbling, find an heiress whose inheritance fortunately comes from trade or some other source, to prop it up. It feels like a heavy weight for the heir to carry. The emphasis here is on responsibility and continuity. However, there’s a snag. What if something happens to the heir? Then you will need a spare – two boys at least – to ensure the continuation of the family line. So, to be on the safe side, most families try not to stop at one.
