OK, I've (really we've, thank to all for the help) traced Arthur Harold back to his parents, and found (in turn) their wedding;
Arthur Henry Gale, b1863, Surveyor married Emily Maud Grossmith, b1870, 5 Apr 1894 in North Brixton Christ Church.
Arthur's father is William Richard Gale, an Iron Merchant (deceased).
This is nowhere near any ancestral lines I know of for "my" Gales.
I am (therefore) merely at a loss as to why the 1950 Dachshund was called Womack, the starting point of this search?!
