All kinds of things show up in Google. I just a listing that shows that the Noorderkwartier admiral's name was actually Pieter Florisse Blom (another way of saying Florissen or Floriszoon), and that his father was Floris Hendrickszoon Blom. Pieter Florissen's wife was Lidewij Teding van Berkhout. Pieter Florissen was born in 1602 and died in 1658, killed in the Battle of the Sound.
