Great to hear from you.
I have a copy of the other letter of Barney's which you mentioned. It was written to his neice Florence Kidd in about 1928. There is also another letter I got recently which describes a trip he made to Connemara to do some building work for Lowry's and was writtn about 1915 - 1920. Both make fascinating reading. I will copy them for you if you wish.
My mother remembers your father well - she just knew him as 'Newell'. It is interesting that you are called Des, as that was my father's name which of course is just coincidence as there are no ties there.
I wasn't aware of the Tatler article. Perhaps if you ever come across it you could send me a photocopy?
There was another Sarah Newell Tedford in the family as you described. It is strange how many families named their children after ones who had passed away. We wouldn't think of doing that now.
I typed you name into my family tree and it transpires we are second cousins!
I have sent you a link to the family tree that I have on Ancestry. I don't know if you have seen this one or not - perhaps you could fill me in with any gaps. In the meantime - take care and I hope to hear from you soon.
