aha!
Thanks Nigel

So ....Berwick on Tweed, that town that has no allegiance to either Scotland or England.
They are Berwickers !

Being the town is just 4 miles, south of the Scot border.
When in England they claim to be Scot, and in Scotland, claim to be Brit.
Nice to have that solved.
Nigel, any idea what the term
"BYE POST" AND
"BYE LETTERS" ARE ?
I am referringt to a letter by Rowland Hill in 1849 (T.P.O Wilson Page 6)
regarding having RPO's on all main roads
"to save bye bags and riding work"
I am presuming mail bags from receiving houses, given to the
lads riding mounted with posthorn?
Not come across that term in 25 years.
Google was not my friend.
