****
Where does the name John Hartnell come from?

The father (Dennis b abt 1786) of this John Hartnell Buckingham (b abt 1816) has a BROTHER also named John Hartnall Buckingham (b abt 1791)
Dennis the elder 1st child b abt 1767 so estimate marr about 1766, and born circa 1746

IN freeREG there is a marriage between Joan Buckingham & John Hartnoll:
CountyDevon; Place Rose Ash
Church name St Peter
Register type Phillimore's Transcripts
Marriage date 25 Oct 1735
Groom forename John HARTNOLL
Groom parish East Buckland
Bride forename Joan BUCKINGHAM
Bride abode East Buckland
Transcribed by John Pingram
Credit Gay Bryne
File line number 360
East BUckland is about 12 miles Northwest of Rose Ash (Both south & North Molton are in between)

Could this be how the name John Hartnell Buckingham enters the family?
maybe Joan is sister to Dennis??? or sister to his father??
from weddind date Joan would be born circa 1715
if Dennis the elder was b abt 1746, then she is more likely his father’s sister

looking for her baptism (Devon 1690-1725) (none have a brother named Dennis)
