Well I am at last at home after our six weeks in the USA and Canada.
As your surname is Ayrton, I can only assume that you are a son or grandson of Harold. I had found an Alan Ayrton born Sep 1926 and was under the impression that he was an only child.
The interesting thing is that I have now located two other descendants of Richard Ayrton. They are Antoinette Doxon who is a descendant of my GG Alice's brother Richard and another, Linda Aldroish, who is descended by my GG Alice's sister Betty. Betty had one daughter Maggie (father unknown)
and Linda is Maggie's great granddaughter.
Antoinette lives in Hythe near Southampton and I visited her in August 2008 and she had the family photo album which was her Aunt Kathleen's who had died May 2003. While I was with Anotinette, her other aunt Ethel arrived. Ethel, Kathleen and Antoinette's mother Lillian were sisters and their father was another Richard born 1897.
Linda lives in London.
I have put in my email address here and hopefully you will reply with yours so I can send you an Excel file containing what I have on the Ayrtons and you might he able to "fill in the pieces" I'm missing or correct anything I have wrong.
