I realise this is a very old thread but in case anyone else is looking.
Some of my forebears came from Atpar/Adpar in Llandyfriog parish, Ceredigion.
My great........grandmother was Esther T. James (b.1776) who, I believe, named one of her sons (my great.........grandfather) Theophilus after her father. There is mention of Theophilus James's daughter, Esther, marrying Samuel Griffiths in a Welsh book of independent church records.
My great great grandfather was also a Theophilus James (1839-1822) and my great grandmother was Margaret Theophilus James before marrying and passed the Theophilus on to my grandfather.
I think Mary from Llandyfriog must have been a sister or close cousin of Esther who also named her son after her father or uncle (if Theo had a brother!). People back then seemed to name every child after an ancestor. There couldn't have been that many Jameses in Llandyfriog for them to not have been related!
The Jameses in Atpar were a family of curriers, tanners and saddle makers.
http://www.genuki.org.uk/big/wal/CMN/Cenarth/Pigot1830Also lists a Theophilus Griffiths as a tanner making me speculate whether he might have had a daughter who married a Mr James and named a son after grandfather Griffiths thus keeping the Theophilus name in the family. It survived in my family until my grandfather died in 1960!
