I was searching for Pieter Floriszoon/Florissen (using Vivisimo.com) and found an interesting page. This is devoted to Jacob van Wassenaer Obdam, who was the son of Jacob van Wassenaer-Duivenvoorde (who had a ship named after him). The best part of this page is the good scan of the Van de Velde drawing of the Battle of Lowestoft. I have not posted such a thing because of concerns about intellectual property rights.
I would not treat this page as a source for detailed information, as what is quoted about the Battle of the Sound is not accurate. The images on the page, though, make this worth viewing.
