I wrote out a broader narrative, but lost it, forgive my subsequent factual telling</br>
At marriage, Margery is said to be of '''St Neot''', stated as a spinster and the witnesses are not the parents</br>
</br>
'''Henry and Mary''' have no records of baptisim at St Neot or surrounds 1775 to 1829</br>
</br>
'''Henry and Margery''' have 2 records of baptisim of a Margery at St Neot and Liskeard respectively.</br>
Margery DUMBLE Baptism 13 Jul 1777 Cornwall St Neot : St Neot : Other Transcript</br>
Margery DUMBLE Baptism 22 Dec 1782 Cornwall Liskeard : St Martin : Other Transcript</br>
</br>
'''John and Mary''' have 1 record of baptisim of a Margery at St Neot</br>
Margery DUMBLE Baptism 11 Aug 1822 Cornwall St Neot : St Neot : Parish Register</br>
</br>
Notably this last record has a comment regarding a private baptisim "Privately 05 June", which may lack a year, but could conceivably be years earlier.</br>
So, I am led to believe that this person's parents are John and Mary.</br>
Anyone have any evidence to the contrary?
