We are descendants of Aert van O. (b.~ 1545). However, if we go through some maternal ancestry lines, then we go back to the Counts of Holland, William the Conqueror and Charlemagne and many more. View our Pedigree charts here: one, two, three.

Research and Development
The construction of a family tree is not simply copying names and dates from other records and then presenting it in text, graphics or in combinations.
Very often, especially in the times when only hand-written records existed, names were written phonetically -in all kinds of variations- or quite illegibly. Books, printed in the 1800s, often had their dates and (first) names wrong about families living hundreds of years earlier.
The construction of a family tree is therefore like working on a big puzzle. Correlating names, dates, places -all in various spellings- from many different records sources. It is a never ending endeavor to make all the pieces fit together perfectly.
We have tried most software programs, but now mainly use GenoPro to record all our new research findings and link the pieces in a complex puzzle. It is our favorite genealogy software program, since it allows you to visually create your trees and place and drag persons and notes on various "tableaus". View here a screenshot of a small segment. Here a screenshot of a small part of the "Arnhem" tab.
For routine entering of data -and adding geographical info and maps- we use Legacy. From those resulting data (gedcoms), we then use the online "TNG" database on our server to present graphs, tables and individual personalia on this website.
