A good portion of the Netherlands, the birthplace of Jan Mangels Rol, the progenitor of the Roll family in America, is below sea level. Because the fresh water in most places was shallow and the land beneath rich, dikes and windmills were built to pump out the water.

Our windmill logo is a sample from the well-illustrated book about all kinds of Dutch windmills: The Dutch Windmill, by Frederick Stokhuyzen.

We chose the windmolen as the logo for The Roll Family Windmill: Genealogy of the Roll and Allied Families because it was most often a poldermolen, pumping water to uncover rich fields for farming. Similarly, rich genealogical sources are being revealed for research. A surprising collection of ancestors have been discovered.

Please remember, though, that everything here is the product of an amateur genealogist: the worst kind. Genealogy, like history, is an art and not a science. Some genealogies are better than others; almost all contain fairy tales. You must not believe anything you read in such works unless you are able to prove the information yourself. Although I believe there are unchangeable systems of truth, genealogy is just not one of them.

I hope you enjoy your visit to the Windmill as much as I have enjoyed the many thousands of hours constructing it.

Who's Who

The paternal and maternal lines in the top menu bar are those of the parents of William Henry Roll, the creator of The Windmill. This family tree is the result of a quarter century of almost daily research.


Beware of facts and relationships without sources, both on The Windmill and elsewhere. Most genealogies contain speculation.
