I'm Mieke Fiers, Wil Fiers' sister. We are from The Netherlands (I'm living in Australia at the moment). The name Fiers is fairly common in The Netherlands (always spelt and pronounced the same by the way ... we pronounce it as "fears"). Unfortunately I cannot tell you anything about the early family history. Some members of my family back in Holland are trying to do the same as you though. I shall try to obtain their e-mail address, so you can contact them with your questions.
