"Massaging" of the age(s) on marriage register entries is far from uncommon, particularly when there was an age difference in the ages of the bride and groom of more than a couple of years.
Just recently I've come across a spate of such, - I guess that it's a statistical thing, - every other record in the last week or so has involved an age difference from the real age of anything up to 6 or 7 years, - but that still doesn't match my personal record a couple of years ago of 17 years being trimmed off an age, but then there was a 40 year difference in ages But I've also had runs of marriage register entries where the ages were spot on
Just y'day I had a groom aged 23 showing himself as 20, with the bride showing her age as 17 when she was really 15
Most often it's only one age which is massaged by more than 2 or 3 years, and most often a reduction, but far from uncommon to be an increase. Again, most often just the one age, but, again, far from uncommon to be both.
Especially for people born before 1855 remember that they wouldn't have a birth certificate. While they, or rather their parents may have had a baptismal certificate, who's to say what had happened to this
Even for people born in 1855 or later, as with the spelling of their surnames, they weren't that bothered back then about their exact age, - in other words, it should not be automatically assumed that all instances of marriage register "wrong" ages are the result of an attempt to deceive.
The analogy that I'd draw is that I'm sure that many researchers are familiar with families where consecutive census entries are immaculate in their accuracy; but, with other families, many of the ages vary a bit, or more than a bit, from census to census Again, I'd argue, most often not an attempt to deceive.
Remember the whole marriage register entry procedure - in the sense that, for the majority of register entries, all that the registrar did was to transcribe the information from the marriage schedule filled in by the couple and the minister, and signed by all three parties. In other words, no proof of age was required by the registrar.
While I'm sure that some ministers/priests required the groom and bride to prove their age, or he knew the ages already, exact or approximate if he didn't refer back to his parochial register, since he had baptised them, - or maybe when it was before his ministry, there was no statutory requirement on him to do so, and, in any case, just how many ministers were that bothered about being absolutely accurate ?!, especially if it appeared to be the case that the couple were roughly of the ages given
In terms of age, when I remarried in Kilwinning in 1993, all that I had to prove in terms of marital status, via the divorce details, was that I was free to marry As far as I'm aware it's always been so in Scotland, outwith situations where it was the case that an age greater than the current legal minimum had to be demonstrated .....
In general, as far as both statutory and census records are concerned, ages, most especially on death register entries when the informant is not a sibling or the spouse, need to be treated with a degree of caution.
That's not to say that other informants in the case of death register entries, family or instituional, didn't get it exactly correct, but the probability that this is the case decreases as the "distance" of the family relationship increases, or the informant is the governor of an institution, or a neighbour, or, - one of my favourite relationship descriptions, - "intimate friend", - which had a rather different meaning back then
Omigawd , - I feel another article coming on ..........
Last thought, - the only statutory record on which the age can be guaranteed to correct is the birth register entry
