William was born in Upton Pyne, just North of Exeter, in Devon, son of William Henry and Ann Hoare. William Henry Sr. was born in Teignmouth, and a Master Cooper, in Teignmouth, in 1871. Ann was born in Upton Pyne.
In 1871 William Jr., described as a Printer/Compositor, was a Lodger in the home of Samuel Cotton, a Blacksmith, in Wolborough, in Devon. Samuel's wife, Mary, was born in Upton Pyne. So she may have been a relative.
He married Caroline Read in the Parish of St John, Waterloo Road, Surrey in 1877. Both William and Caroline gave their address as Waterloo Bridge Road, right in the heart of London. He was described as a Stationer, and his father William as a Cooper.
Caroline was single, born in 1850, in Romsey. Her father, Merritt Read, was a Photographer. She was the eldest of their four children.
In 1871, the family was living in Church St., Romsey. Caroline, at 22, was a Dressmaker, as was her younger sister Emily. Their brother, Edwin, at 18, was a Shoemaker.
By 1881, William and Caroline had moved to Saunders Road, in Hammersmith, where he was a Printer.
In Broadway, Bromley, in 1891 William, still a Printer, was now Manager of a Machine Agency. With William and Caroline was their adopted son, Frank Hoare Shill, aged 10. He was born in Chertsey in 1882. Francis, Caroline's younger sister was also there a Dressmaker, single, aged 30. They also had a Domestic Servant.
By 1901, William and Caroline, with Frank, were still in Bromley. William's parents William and Ann, were also there, William Sr was described as a retired Cooper. Frank, at 19, was a Clerk and Collector of Accounts'.
In 1911, William and Caroline were living at 10 Burlington Terrace, Rowlands Road. William was an Agent (Domestic Machinery), and Caroline was Assisting in the Business'.
Frank was now a Directory Canvasser, for Kelly's Directory, living as a Boarder in a house in Sutton. (He was married in 1908, but I haven't found any details of this.)
In 1921, William was described as Branch Manager. Domestic Machinery Depot. Messrs R. Nelson and Co. He and Caroline were still living in Rowlands Road.
When William died, aged 76, living at 13 Grafton Road, Administration was given to his widow Flora Hoare. There is a record of a marriage between Flora Wise and William H Hoare, in 1927, in the East Preston area, and a Flora Hoare was buried in 1949, in Durrington Cemetery. That was a late and short, re-marriage for William!
