Yes indeed, that's the Klapwijk family crest above. The "Klapwijk Genealogical Society" commissioned the design of a family crest a few years ago, based on historical information. There's an active Klapwijk Genealogical Society in the Netherlands that details the origins of the family name. Basically, the first use of our family name can be traced to the 1500's and the use of marks on farm houses and buildings was very prevalent in those days. Some of the old literature appears to indicate the use of a "Drudenvoet" (Druid's or witches' foot) and the crescent moon as marks on early family sites. The picture of the crest was originally "pinched" from a relative's former site in Holland (bedankt Peter), but since then I ran across the former site for the Reunion Usersgroup (a Mac based genealogy program), and there I found a slightly larger (and better) version. I stumbled across these sites when, just for fun, I did a Yahoo search on my last name a quite few years ago now in the days before Google's dominance, Peter's site was the first match out of 147 and the Reunion site was the last one. The Reunion site was done by Dick Klapwijk. Dick did a tremendous amount of genealogical research on our family and wrote "Vier Eeuwen Klapwijk", a book that traces our family history from the first use of the name "Clappwijck" in the early 16th century to the present. The town I grew up in, Pijnacker, is a key part of our family's history and as you can see from the pictures below, a couple of roads in the area, as well as a subdivision, are named after us.
