This looks like Mary's death:
Mary Bather, aged 70. March q, 1832, Conway, vol 11b, p 673
and it looks as if daughter Mary married a Robert Jones, Dec q, 1913, Conway, vol 11b p 846
son Hugh J Barther served WW1 in the Welsh Guards and the Royal Welch Fusilliers - Reg Nos. 1439 and 222 (medal card only)
son Edward Barther served WW1 in the Bn RWF, Reg No. 479 . I've found his service record (He was 5ft 4 1/2 ins and demobbed 2nd March 1919) Not sure if this was not TA or not

His mother, Mary, is down as next of kin. He was a postman
