Hello Nigel.
I might be barking up the wrong tree here, but thought it worthwhile dropping you a line like this - just in case.
I see you are researching a Richards/Davies line, and also a seperate Llangyfelach (nr Swansea) Glamorgan line. Reading through the thread, I also see mention of Benjamin Richards (not too common a name in Wales) and also of carpentry. All of these points cause me to consider a connection to my own Richards/Davies research.
I am a direct descendant of David Richards (a carpenter) and Sarah Davies, both born around 1796 OUTSIDE of Glamorganshire (according to the 1841 census), although I've yet to locate their birthplace and birth entires. I've also yet to confirm their place of marriage (the IGI throws up a possibility in Myrthyr Tydfil). Their son who I am descended from was Joseph Richards, born c1838 in Llangyfelach.
Josephs older siblings were HENRY (born c.1826), ELIZABETH, (born c.1826), and JOHN (born c.1830), while his younger brother was BENJAMIN (born c.1840).
I've tracked the family through all the census returns - my own branch heading to the North East of England by 1871 (Durham & Northumberland), and eventually settling in Middlesbrough (then in North Yorkshire, now in Cleveland).
The names Henry, David, John, Joseph and Benjamin appear each generation.
I'm wondering if you've encountered a carpenter called David Richards in your research? Perhaps linked to a Sarah Davies? Have you seen any Richards information at all during your Llangyfelach research?
The only record I have of David Richards alive is the 1841 census, where he and his family lived at the YNYSPENLLWCH TINWORKS. He had passed away by 1851.
Although listed in the census returns as being born in Llangyfelach, I've found no birth records for HENRY (born c.1826), ELIZABETH, (born c.1826), JOHN (born c.1830), JOSEPH (born c.1838) or BENJAMIN (born c.1840). Maybe you have transcripts on CD for this area? Or know someone who does?
ANY help or advice greatly appreciated. It took me 14 years to get this far (my Joseph married a Gypsy in 1871 and went travelling!) and a further 3 years of looking has not got me further.
Again - ANY help, advice, or a point in the right direction would be greatly appreciated.
Best Regards
Curtis
