Hello Libby
I don't know if this of any use but it is list of players who played for
the Welsh first Rugby team
http://en.wikipedia.org/wiki/List_of_Wales_national_rugby_union_players
(note: being Wikipedia it's accuracy can't be guaranteed). It lists date
of their first match and then subsequent number of caps etc. If you open
up the web page press "Ctrl" and "F" and then type Francis in the
search
box that comes up there are 2 Francis's listed.
A Gwyn Francis from 1919
A Peter Francis from 1987.
If the Gwyn Francis there is more about him here
http://en.wikipedia.org/wiki/Gwyn_Francis.
If Peter Francis there is photo of him for sale on e-bay!
http://www.ebay.co.uk/itm/PETER-FRANCIS-WALES-AUTOGRAPH-RUGBY-PHOTO-CARD-....
However I think Peter Francis is still alive:
Peter Francis
Wales
*Full name* Peter William Francis
*Born* July 9, 1957, Cowbridge
*Current age* 54 years 332 days
*Major teams* Wales
*Position* Prop
So by a process of elimination /Gwyn is the only likely match/.
Does this fit in with what you know?
