I've seen his birthdate listed as 7 Apr 1683; 7 Apr 1688; and 1675. All three dates seem to be, UNSOURCED. So where did the 7 Apr 1683/1688 come from? I have searched high and low with NO DEFINITIVE explanation. Personally I believe, Cornelius II was the son of Cornelius I and his FIRST WIFE "Eedeth Moryson". especially in light of the simple precept that most juniors are named such as they're usually the first sons of seniors.
