I live in Canberra in Australia, but come from Sydney originally.
I was thinking of the actual town, since I remember places like Ware, Hertford, Rickmansworth etc which are near Hoddesdon. I was curious how close you are to it; it is 15 miles north of London which I think puts it in South Hertfordshire. As I mentioned before, if you would rather not say then that is all right.
I discovered just a few days ago that Hoddesdon was right on the border with the Danelaw. There are a couple of places there with Danish names. So it was right on the frontline.
