I have added a document to the sources tab that shows Coenraet de Visscher's wife to be Maria Schuyl de Visscher, NOT the 'Akke Jans Tiesema' listed in all the other Myheritage family tree 'sources' for Coenraet de Visscher. Akke married a different 'Coenraad Pieters Visser' in 1811, that record can be found here: https://www.familysearch.org/ark:/61903/1:1:QLR1-HTTR
It baffles me how easily people will just add crap from MyHerritage user trees without checking the information, and what makes it worse is everyone just copies the same false information from everyone else.
I checked this line about 6 months ago very briefly and thought I had confirmed all the sources up to Philip V of France, but on closer inspection the last few days I noticed some names had been changed in the line, either through bad merges or somebody deliberately fudging people and information out of some moronic need to tell their friends they are descended from royalty. The same thing happened with the van Wyk line to Edward II of England.
If somebody has any documentary evidence linking Coenraet de Visscher with his supposed son 'Jan Coenraad Visser' then please share it, as without this proof there is no descent from Phillip V of France.
