I try to help you through the site, but I can't translate everything. Maybe you could write the City Hall/Archive and ask them to help you out. But part of the site is available in English !:
click: stamboomonderzoek (=familytree research)
click: Digitale Stamboom (=digital familytree)
select option UNION JACK which gives English info from now on!
You will be transfered to the English search window that will guide you through it from now on
