really what is the point of taking this quiz by copying the answers.. (Now if there was some grand prize to win for those that get the most points on this site or something, I would still find it stupid, but atleast get the motivation.. in this case there is nothing to gain from cheating..)
I think in many places names have been very unoriginal and limited, sometimes even with brothers of the same name. That has become less and less and I think around 2000 (there is no abrupt line but by then it was a majority) people started naming their kids original things. I think part of it is, religion in most places does not dictate everyday life anymore so biblical names and naming after saints becomes less.
plus the world has become much "bigger" definitely with internet but also because almost everyone has a car now. Nobody normal would use to see the world beyond their town, so traditions and family were a bigger thing. Not that they dont matter now, but it used to be all encompassing.
Harold comes from the roots for army (here (not pronounced as the english word here but more like herre) and rule/power (wald, compare wield)
So definately not the same name. Of you course people can gives other people any nickname they want. (Some people give others random names, like calling every new person in class bob or something eventhough they are called mitchell) But Harold and Hen(d)rik are two distinct names.
