Arthur looks like her son from the census entry but a birth certificate is needed to confirm this.  He was registered at birth as David Arthur in Q2 of 1897.  He was still alive and a coal miner in 1939, birth date of 29 Mar 1897 and married but his wife was not in the Register; Dorian J Puntan who was listed in the line below his and born in 24 July 1933 may have been his daughter.  David A Puntan married Margaret Bryant in Q4 of 1924 in Pontypridd, Glams.

From this 1939 Register entry for the above Thomas Puntan’s household, Thomas, Sarah Anne’s sister, was born on 5 Feb 1870 and was a Foreman at the tinplate mill.  Thomas died in 1945 aged 75.

Her death cannot be clearly identified.  Oy might have been before 1911 as in 1911 her daughter Mary Ethel was living with Sarah’s married sister Adeline.
