I think there must be many cases where a less than the usual love-match was made, simply so that people could live together companionably, with perhaps domestic and financial benefits for both parties.
I can recall 2 examples from the 1950/60's in my immediate neighbourhood:
- a spinster in her 50's married a rather fragile chap of delicate health- both seemed happy with arrangement.
- a lad in his late twenties who had always been very asthmatic and delicate wed a lass of similar age who was rather lame, having a pronounced limp. They did not have children but set up a happy, prosperous household.
There were and are many versions of what a Marriage can be.
