There is a marriage record from Utrecht for a Emilius van Cuilenborg https://www.wiewaswie.nl/en/detail/48179917 which would make this man's DOB 1650 or earlier, which is possible for a Dominie who died in 1704. Or it could just be a namesake.
Dominee is just a title. So his name is Emilius von Cuilenborg and he is married with another woman. And Emilius van Cuilenborg was at the moment of marriage in Utrecht.
IMHO this is not a match. Also he is a von not a van. The von indicated that he is from the German branch of the Cuilenborg family. And also the noble branch.
Jeroen,
There is nothing to suggest that the Dominie's position was only filled by men born on the island. The earliest (only) record i have seen for Dominie Emilius is his death in 1704, it is possible he married one woman in Utrecht in the 1670s then at some point in the next 30 years married again and moved to Canvey.
The difference between van and von could be important evidence, or could be a transcription error, or a spelling mistake, or ignorance of Dutch names by the original author.
I think this is a definite Maybe.
based on a PM I sent to Alex earlier today, I am sure that the marriage record found by Jeroen refers to the same person.
As can be found on http://www.verkade.nu/dominees.nl/search.php?srt=g&id=11502 he worked in Heusden from 1678 until 1692 and then went to London
I would not try to read too much in the use of "van", "von" or the omitting of this word. Even in the 19th century they were rather sloppy in the spelling of names; as long as it was phonetically correct it was acceptable. And for earlier times, such as the 17th century, that holds even stronger.
