There is a link between Norfolk and Devon -
my mum is a norfolk Davy and family tree goes well back
i had a lot of help from a Devon Davy
anyway - i live 5 miles from Ingoldisthorpe and the church has the shields etc of the Davys in the 1800's who were at that time the senior Davys and the elephants are there
when Sir Humphrey was given his gong he had to get permission from the Ingoldisthorpe John Davy to use the heraldic signs.
the Welsh connetion i had heard of but not the link.
i am not able to access my records at the moment but will
report back when i can A
