To update you all on my research and pose another question (sorry!)
I have Elizabeth’s death certificate – she died at 24 from consumption.. She WAS formerly Roberts, as was Hannah. Hannah appears to have married George in 1873 (certificate to be obtained).
I now have a birth certificate for a George Arthur, whose date of birth ties in with the ages given on the 1871 and 1901 census returns BUT his PLACE of birth was not as expected. It is shown on the census returns as:
1871 Glyn Ceiriog, Denbighshire, Wales
1881 Glyn, Denbigh, Wales
1891 Denbighshire, Glyn
1901 Denbigh, Glyn
I have been assuming that “Glyn” refers to “Glyn Ceiriog”, as in the 1871 census. However, the birthplaces given for his second wife and eldest daughter in the same transcription are also “Glyn Ceiriog, Denbighshire, Wales”, but I know the eldest daughter was born in Nantyr, Denbighshire, as were subsequent children (as borne out by birth certificate/1891 and 1901 census images).
So, is the 1871 transcription for the family misleading? Has perhaps the transcriber assumed it was Glyn Ceiriog

Could my George be the one whose birth certificate I have, showing him born in Glyn Triain (very nearby), not Glyn Ceiriog?
What do you all think?

(It would be nice if it was him, as he shares a birthday with one of my sons!)
