I am descended from Jan Frans Montenak. In his first marriage there is an additional name after Jan Franssoon Montenakel. It has been transcribed as "Van Weert" on the the website "http://rotterdam.digitalestamboom.nl" You can see a copy of the entry at this link :- https://dl.dropboxusercontent.com/u/29929993/Jan%20Montenack%20-%20marr%201630.jpg However looking at other letters "e" in this entry I do not think it is "Weert", but maybe something like "Wissit". I would appreciate any opinions on what this name is? Thank you Simon in Tasmania
