Thomas and Emma had a large family, as follows:
3.2 Percy Laurence Laycock (1883 - 1962) married Irene Wright Strong (18 November 1885 - 1982) in 1913
3.3 George Edwin Laycock (1885 - 1961) married Zoe Blakey (10 December 1887 - 1976) in 1917

The following obituary appeared for Rachel in the 5 October 1928 edition of the Auckland Star:
An account of the premature death of Henry Grubb appeared in the 12 February 1889 edition of the Auckland Star, under the heading "Thames Notes":
FATAL MOTOR ACCIDENT AT PUHOI.
8.5 Alfreda Barclay Robinson (1896). Alfreda died in 1942 and never married.
10.1.1. Gayzene Florence Mary Keven (1915 - 1950). Gay married Stuart Monteith Doull (15 February 1911 - 2002) (second son of Mr and Mrs H.M. Doull of Richmond, Auckland) (after becoming engaged in February 1937). Unfortunately the marriage was not successful and by April 1945, they were divorced. Only five years later, and very prematurely, Gay died aged just 35. I'm unsure whether or not they had children.
