Costijn I van Zierikzee, heer van Renesse, Lord of Renesse

https://encyclopedievanzeeland.nl/Heren_van_Renesse

Please don't use unverified popular sources ! From which source is the name 'Constantijn' originating. ? Furthermore: why is Costyn a son of Jan which was 'Heer'(lord) of Renesse. Renesse came in Costijn's possession through the exchange of goods between Arend IV and Costijn, which possessed 'Zierikzee' before the exchange. Therefore the conclusion that Costijn was a son of a "heer van Renesse" is false I think ! And all the concessions in describing a 'profile-name' between managers at geni.com in order to satisfy everyone may definitely be wrong, not to say resulting in falsifying 'history' (these remarks made by manager RvO)
