The will says that Hendrik junior has “absented himself from Holland where he had been for his education so that no tidings from him have been received by me for several years.”
It turns out that Hendrik senior wasn’t the only person concerned about Hendrik junior’s whereabouts.
I’ve just found the following in Amsterdamse Courant of 10 May 1800, found in the MyHeritage Netherlands Newspapers, 1659-1899 collection.

pleasure to be helped when they are in person or per Missive. Book seller is supplied.
Hendrik senior was born in Doorn in 1750, and arrived in Demerara about 1773. Hendrik junior could well have been born not long after, which would feasibly have him at about 20 in 1794.
The J. ten Brink making the enquiry is quite probably Jan ten Brink, book store owner and publisher. Netherlands Wikipedia has an entry for him. I wonder why he was being enquired about? Did he owe money?
