George Tate's sister Elizabeth was my wife's Great Gran - she lived to 97 so my wife knew her quite well.
There is an article about their mother Annora (known as Norah) and about both George Tate's in the Beverley Guardian of July 27th 1935 (my in-laws have a copy of some sort). Also a photo of four generations of the family appeared alongside the article.
Annora's first four children (George 1870, Florence 1877, Mary Ellen 1878, Elizabeth 1880) were with Robert Tate, who we believe then disappeared, which is why she was later unable to marry Anthony Taylor, who she lived with. The four children with Anthony Taylor I believe had Tate as their surname, but Taylor as their middle name (Hilda 1885, Anthony 1887, Thomas 1889, Muriel 1892). The way they responded to the census was interesting (!):

Annora was the daughter of William Cooper and Ann(a) Wa(r)ters, she was named after her aunt Annora Cooper.
Elizabeth Tate, my wife's great gran, married Joseph Harland and had just one child, my wife's Gran Beatrice Annie Harland who was born in 1906.
I have only limited details of the other Tate descent lines (and a complete lack of death dates) and would be interested in knowing more. I do know George Wilfred Tate married Elise V Whitaker in 1924 and had a son Dennis, born 1925. Muriel Taylor Tate married John H Walker in 1913. Hilda Taylor Tate married Henry Goulton in 1920, sons William 1922 and John c1925.
