Through the presentation of these genealogical information on the Internet, I try to exchange ideas and
information with the visitors of this site, to give a helping hand to beginners and to give the advanced a handle.
Given the large amount of data, you might think that it is coming from a scratch lot. It seems to me therefore
correct to state how this amount of data has been reached. The vast majority of these data comes from reasonable
reliable secondary sources like Genlias, from serious genealogical periodicals like Ons Voorgeslacht, Nederlands
Leeuw, Gens Nostra etc., from transcribed church-books, from serious genealogical CD-Roms and so on. About 5% comes from
consulting original documents and the last 10% I have received from serious fellow genealogists. I think that 95%
of the information is accurate, but only 5% is sure. I am controlling the remaining 95% on the basis of the
original documents, but given the large amount of work, I think I will never realize this goal. Especially
the part before 1800 and also the pre-churchbook-section, contains a number of assumptions that are plausible, but not
100% sure. Any response from you I will be grateful for, because in this way we maybe will be able to come to better
conclusions. I still have a lot of material to expand the database in the future. I will also control the
facts, but nevertheless, errors are never excluded. If you detect an irregularity, please be so kind to
inform me, with your cooperation we can this database, which so many people enjoy, keep as correctly as
possible.
Everybody is free to take from this site the information he or she intends to use for no-commercial use, but in the event
of an error or if you have a supplement, a message would very much be appreciated.
