The 1911 census confirms that John Thomas Winter (b Houghton 1860) and Ruth Leadbetter (b Benfieldside 1862) married in 1879 and had 16 children, 13 of which were still alive.
I've found most of them via BMD & census records but am struggling with the last two, who I assume must have been born and died within census years (the third death is Ada Elizabeth in 1903). The children I have so far are (deep breath):
Mary Isabella (Jan 1880), Alice (Oct q 1881) & Ada Elizabeth (Apr q 1883) - Houghton Le Spring
Ruth (Jan q 1885) - Ebchester
John George (Jan q 1887), James Chadwick (Mar 1888), Robert Christopher (Jan q 1890), Thomas Snowball (Jan q 1891), Joseph Ernest (Apr q 1893) & Albert Edward (Apr q 1894) - all Allendale Cottages.
William (Mar 1897), Samuel Taylor (Dec 1901) & Elsie (Jan q 1904) - Cornsay
Edith (Oct q 1906) - Chester le Street.
The obvious gap seems to be before & after William, and after ruling some out I think I have three possibilities, all in the Lanchester registration district:
Christopher 1895-1896, Rochester 1898-1898 & Lillian May 1899-1900.
The first two don't feel right - Christopher has already been used as a middle name and Rochester just doesn't sound right for a mining family.
Can anyone help me either rule in / out any of the above, or perhaps provide some alternatives.
Many thanks in advance
