Here are two notes from Murray
Brereton, from New Zealand.
Dear Bruce, I also have a book make she sent to me I think belonged
to the last lord Brereton, the interesting thing is I have letters
from My great-great uncle Dr Samuel Brereton sent from India with
the same crest embossed on the letters and envelope. What do you know
about the different Brereton crests?
Subject: Brereton manuscripts
Re. MONTAGUE-SMITH, P.W. (ed.) was the editor of Debrett's Peerage;
He was a decedent of the Irish Brereton s and had been writing
a book on the Breretons. Unfortunately he died app. 15 years ago.
His wife has sent the manuscripts to the London genealogy society.
(She was a cousin of my next door neighbor)
I don't know if any body has had access to this resource and would
be interested to know if they have.
