This 1907 photo of the Silas Waymouth family includes Helen at the left hand end of the middle row.   Nell was the wife of Arthur William Waymouth (back row, left end).   Their first child died soon after birth.   Their daughter and son followed (both seated in front row).
Nell died the year after Arthur.   Her probate said that she was of 25 Iverna Gardens, Kensington, London, a widow.   Probate was to her daughter Dorothy Glanville Whateley-Smith and a doctor.
