Henry Boniton Burton - Birth of son

Reviewing online, all the profiles of this person seem to make the same mistake. Given the precision (as opposed to the accuracy) of the assertion, I'd be tempted to say that the death dates are more correct. But I've not seen any primary source information supporting either. Suggestions?

I have no suggestions, given that people use others' trees as proof. To me, geni is pretty much a joke for the most part, prior to the Colonies in the 1600s.
