I ordered two books that Nico Brinck recommended to me

Nico Brinck decided it was too hard to try and fill in gaps to my list of ships and captains about which I have missing information. He recommended two books, instead, which I ordered. One of them I may already have, although I could not find my copy. The book is Thea Roodhuyzen and is titled De Admiraliteit van Friesland. I don't remember the title of the other book, but it is by an author who has written about Zeelanders and the WIC and EIC (VOC).
