The baptism date on the profile of John Whinham needs clarification – see the baptism note in the bio.

Any member with access to Northumberland baptism records to clarify would be appreciated.
It’s not unusual for slight differences in date to appear in death or census records. Especially if they were illiterate. Death record info is often given by younger generations who sometimes just have a stab at dates. ancestry has this
Ancestry.com. England, Select Births and Christenings, 1538-1975 [database on-line]. Provo, UT, USA: Ancestry.com Operations, Inc., 2014.
The fact that "England, Select Births and Christenings, 1538-1975" on Ancestry agrees with FamilySearch is not actually independent confirmation, as Ancestry got that collection directly from FamilySearch. The next line on that record after the Source Information says "Original data: England, Births and Christenings, 1538-1975. Salt Lake City, Utah: FamilySearch, 2013."
