I have not found all the family in 1891, but Constance (the L was for Letitia) and what appears to be a sister, Ethel May, are aged 14 and 9, respectively and are pupils ata school in Kirkley, Suffolk (nr Lowestoft). In 1901 the family are back in one place in Chiswick, no more children – however Horace’s birthplace is now Norwich, not St John’s Wood. In 1911, Emma May is still with her parents, who now live at 89 Uxbridge Road, Ealing. Horace was a manufacturer’s agent for preserves and confectionary, & were living in an 11-roomed house. So there was a connection with preserves, and if you dig deeper you may find the company for whom he was working - might be Hartleys? Would be difficult to track that down as he was an agent and could have been working at some distance from the manufacturing sites
I believe that Catherine was nee BOND, married Henry K in 1790 at London St Clement Dane, had possibly 12 children and then died in 1829. Henry married secondly to Lucy POWELL a widow, and seems to have had 2 further children with her. Henry was a ham dealer from at leats 1816-1829 and was a ward beadle for St Gregory by St Paul in 1833. He died in 1839. I have nothing on Henry's origins though
