Uncle Reg

Recently I was contacted for the first time by a long-lost cousin,Sally,whose father was my Daddy's first cousin.I used to live in Hertfordshire nearby to her but never knew then.Sally is the same age as me and when she contacts me it makes me very happy.She seems a happy person too.I'm hoping when she's ready we can meet up.My sister remembered Sally's grandfather visiting before I was born.She also remembered that this man had a bad leg.When I mentioned this to Sally she confirmed that her grandfather had lost his leg in WW1.As he was my grandmother's brother it seems reasonable to believe that my Dad was named after his Uncle.Questions like... I wonder what they talked about when they met?...and how did Uncle Reg know where they lived?will probably never be answered.
