Dictionary of National Biography 1921-1922
Sir Cornelius Vermuyden
Reading through this biography of Vermuyden I do not think I found any mention of Canvey Island. But it is interesting to read more about his life.
Vermuyden was born in 1595 in Tholen, Zealand and was the son of Giles Vermuyden. In this document it states the earliest authentic mention of him was in 1621 but he is thought to have influence from as early as 1612.
I have seen several dates for his death, namely 1665, 1677 and 1683.
We have not yet found any proof that he ever actually set foot on Canvey Island.
