There are two family trees.
One with the descendants of Lijsbert Jans Cuperus and one with the descendants of Ynze Pieters Tigchelaar. They are seperated, not only because of the easy-reading, but also because the connection between the two is not certain. Click on the correct item in the menu.
On the page with the dutch translation is a link to the family tree in de “friese” language, the language spoken in the north of Holland.
There is also a graphical representation on all pages.
