Finally after many questions elsewhere I’ve got an answer. It was a very complicated issue for me personally. Having lived in England for most of my life I have finally found out that some of my children are entitled to a Dutch passport. I’ve always regretted that certain restrictions stopped my heritage could be passed on. Unfortunately two of my children don’t automatically have Dutch nationality but now I know how they can get it. The other two, due to changes of rules, can still apply for a Dutch passport. Especially with disastrous Brexit it felt such a relief that those two can still apply to an European passport.  Thank you Kris for all your help!
