Hi Angy,
I have visited the WGAS today and searched the burial register for St Peter's Cockett from 1941-1952
and there are only two entries for a Eliza/ Elizabeth Griffiths. One in 1945 and the other 1951.
the first and most likely is Eliza Jane Griffiths, of White Bungalow, Cadle, Fforetfach, Swansea.
July 22nd 1945 aged 72 yrs. date of burial July 25th 1945. Grave number N:E: 94.
the second is Elizabeth Griffiths, 37, Granogwen Rd, Mayhill, Swansea. August 2nd 1951 aged 83yrs.
Grave number E: 491.
Kind Regards,
Rob.
