Hello Gherardus. Thanks for your reply. I found more information than I expected, enough to start a lemma on Feroni. Tensini is of course an Italian family that lived in Antwerp, but several or all moved in Amsterdam, and some left in 1672, as did Feroni. I will let you know more about my experiences in a few days, when I found out more about Feroni. Taksen (talk) 18:03, 21 March 2010 (UTC)
