It took some effort to find Kate's full name. The GRO marriage index had five names on the relevant register page: three male and two female. Neither female was named Kate as I expected from examining the 1911 census. I was able to match up two pairs of names with the aid of the 1911 census, leaving William PLUCK with no partner.
Fortunately Kate left a Will when she died in 1961(see below). Working on the basis that Kathleen Dorothy MITCHELL was her married daughter I looked for the birth of a Kathleen Dorothy PLUCK in the GRO birth index in the period after September 1911 (when the mother's maiden name first started to be recorded in the index).
I found Kathleen D PLUCK in Q1 1912 in the Wandsworth registration district where I expected the family to be living. The mother's maiden name was WALLER.
It didn't take too long to find a Kate WALLER born about 1880 in the Streatham area: Q1 1881, Kathleen Lucy WALLER, Lambeth, 1d, 521.
WILL: PLUCK, Kate of Southwood, Oldfield Road, Bickley Kent widow died 22 December 1961. Probate London 29 March to Frank William Pluck accounts clerk and Kathleen Dorothy Mitchell married woman. Effects £5014 14s.
