Mr. van Eijbergen,
My name is Robert Eibergen, in North Carolina, Us. I have only recently began researching my father's (Bernard Eibergen) family history. I have found a lot of information via your excellent book on the Stieltjes family. I have used a Dutch Dictionary to translate a lot of the information. I have begun using Derx as a nickname, as it appeals to me.
My father would never talk about his family of origin, so I have been happy to learn a lot through your efforts. I believe you may have communicated at one point with my brother Patrick, who lives in Chicago.
Thank you very much for all of your information.
Derx aka Bob Eibergen
