Annie S? How about Annie Smith Osborn m. in Holborn Sep 1878 quarter possibly to Henry John Maryon. I find the other two listed possibles, George Capon, and Thirza Papworth Leet, together in 1881 which makes this (the only Annie with head of household Henry, despite the change in his middle name) possibly yours:
Henry W. Maryon, 29, b. Shelly Ongar, Essex, House Painter
Annie, 22, b. Birmingham
Henry, 1, b. Holborn
Annie Smith Maryon d. Mar 1892 quarter (freebmd) and Henry Maryon with children Harry, 15, and Emily, 13, I think is the one b. 'Higher Ongar' living in Morden Entire, Surrey, in 1901.
