Hello Pam,
A member of the family wrote the Edwin Samuel info onto the family search
site. We can find no trace of him at all apart from 1850 when he was a member
of the mormon church in Llansawel. I have him from 1851 onwards. I did look
at the Samuel Samuel entry you mentioned but can find no connection.
Edwin married Elizabeth Watkins of Brecon Vaynor parish.Elizabeths father was
William Watkins and mother Margaret Martin both of that area.William died in
1844.
Thank you for searching for Edwin.
All the best Gaynor
