John Conklin is widely said to have been the son of Ananias Conklin (Conklin-72) and to have been born in Nottinghamshire, England with no evidence to support the statement and quite a lot of indications that suggest that he was more likely a Dutch settler than an English one.
I only got involved with the family because there were various errors thrown up around it on my county list, but I'm very bad when it comes to rabbit holes.
I've written an up to date view of these two Conklin families and the possible origins of the English side. It's at Space:Conklin_Families_of_America . If anyone can add further to this, please do so.
As far as this John Conklin is concerned the most significant thing is the y-DNA study, the results of which are publicly available at family tree DNA. Numerous descendants of this John Conklin have tested and show good matches to each other.
None of these descendants match with the descendants of Ananias Conklin who have tested, nor with the descendants of Ananias' possible brother, John (Conklin-705), who do match one to the other.
The degree of the mismatch is so large and so uniform that the inescapable conclusion is that this John Conklin was not only not the son of Ananias Conklin, he was not even remotely related to him.
In my opinion he needs to be disconnected from this incorrect heritage. The ability to do that lies with the New Netherland Settlers Project.
