Hya Slowhands,
Looking at my records I think that Rowland Griffiths was my Gt uncle. My Grandmother, Gertrude Griffiths was the Daughter of William Griffiths(Son of Solomon) and Phoebe Annetts. She had a brother named Rowland, born in 1875. Is Rowland your grandfather? If so, we are second cousins. What do you think?
Regards,
Michael.
