Unfortunately, I am not an expert on this subject but can offer a thought. Perhaps some of the people you mention weren't really married. I have come across quite a few cases of people seemingly purporting to be a happily married couple but they were not. I have found this with some of my own ancestors.
One couple amongst my own ancestors had their first child in 1847. They married two years after their sixth child in 1859 and then had another three. In all their children's baptisms they appear as if they were married. Why these ancestors chose to marry at that particular time (12 years after first child) I will likely never know.
When I first started doing family history I was taken a bit by surprise by this type of thing as I had somewhat of a idea that Victorians would fit my stereotyped idea of Victorians.
Perhaps having a certificate wasn't as important to some people back then as we might think.
One party of a couple may have already been married so they may not have wanted to risk being found out in a bigamous marriage. Divorce would have been no easy option in the distant past.
