Hello Back again

Took your advice and ordered a copy with the GRO.
Well that has arrived and im now more confused than ever...

I think I need to start from scratch and forget the family mentioned above...
I have Benjamins date of birth as 2nd April 1854.
Place of Birth, well on several of the census returns it is St Clears, on one it is Llandwr,and another it is "The Roses" which made me think Red Roses.
The copy certificate which arrived is for a Benjamin Thomas born in Llangynnin (which I know is just outside St Clears) but different birth date.
I think the next step is to find his wedding certificate to find out his fathers name for sure.
Thank you.
