Sorry, i have no answer, about the parents from Joannes (Jan) Koopman.
From the earlier item it is known that they married at Velsen in 1795 and that they both lived there then (message from JP Ouweltjes). There are acts of indemnity for those who wanted to settle at Velsen (including some German ones) but I don't see theirs amongst these. It's true I only had a quick look and did not go back further than 1790. I suppose not everyone had to hand these in anyway though and don't know what happened to these when the person involved left the town (even for Amsterdam, where I seem to recall these documents were not required). link
