One key question I'd have is what the 1850 census says.
Who the informant on the death certificate is would also be relevant.
I'd recommend adding sources to the profile. Since it only has the Find a Grave memorial at the moment, there's really no evidence about birth at all. If the evidence about his birth is inconsistent, adding a research note discussing the evidence would be useful. That might also keep people from changing the birth--or might lead someone to discover better sources for his birth.
