This is a while along since your post. My Great Grandparents were Llewellyn Evan Argyle Griffiths and Louisa Caroline Griffiths (Born Aldridge). I have one good photo of them. They were the parents of my Grandfather John (Jack) Sylvester (1903 -1931). Sadly he died when my mother was only 2 or 3 and just before my Aunt Jackie was born.
My mother Valerie, who is still alive and 90, was born Griffiths, but she has always been curious as to why the Argyle was dropped from the family name. and I cant go back further than Evan Griffiths & Harriet Argyle.
Can you shed any light on this?
