Electoral roll Q

[Merry]

I know the age of majority was switched from 21 to 18 in the UK in 1970.


I have a woman registered for birth in Q3 1943. She seems to have been married in Q2 of 1961, So probably aged 17, though in theory she could have just turned 18. She then appears in the e-rolls with her husband in 1962, 63 and 1964. The first of these entries shows a bold type Y against the entry, which I thought meant that some time during the lifetime of the register (so 1962/3) the person would become an adult.

I'm bothered that the Y annotation is showing for the e-roll for 1962 when her age would have been either 18 or 19. I know the data might have been collected in 1961 when she might have been 17 (almost 18 if the info was collected immediately after the wedding) or 18, but did the Y refer to turning 18 or 21? If it's 21 then this can't be the right person, but I'm struggling to convince myself it's not her!
