Hello,
Thanks to everyone who has replied so far. The information has been really helpful. I now have a good deal to follow up on.
I think Ernest Browne must have lived to a grand old age if he was born circa 1855 and was still alive circa 1930.
T.H. Griffiths is one of the more vague ones. He might well have been Thomas, but it is very difficult to link these people with lawn tennis even when their first names are known.
