Harry Shelvoke was one of the founding members of the British coachbuilding and engineering company Shelvoke and Drewry. He was one of the last members to bear a family name that is documented to have become extinct in modern times (the last person bearing that name died in the 1960s). The name lives on in only three company names connected to Harry's family: the two engineering firms of Accles & Shelvoke, Shelvoke Ltd (Dennis Shelvoke / Dennis Eagle) and Shelvoke Pickering and Janney, a firm of chartered accounts in Cannock, Staffordshire.
He is descended from those associated with Manor of Shelvock in Shropshire and families bearing the name of Shelvock. Historical records show that the spelling variant of Shelvoke is first recorded in 1722 at Eccleshall in Staffordshire, NW of Stafford, before recurring in the 19th-century industrialised West Midlands towns of Wolverhampton and Willenhall, probable ancestors of Harry.
James Shelvoke, Harry's grandfather, (born by 1815, location unknown) headed the family centred in nearby West Bromwich and Aston, part of Birmingham. James married Catharine Harper in Aston in 1833. They had three children:
(George Edwin Shelvoke, Harry's brother, married Charlotte and had Gwyneth (born in Cape Colony, South Africa c. 1900) and William George (c. 1907; who is believed to have married but had no issue). In the West Midlands, 1907 appears to be the last birth year of any Shelvoke.)
The firm of Accles & Shelvoke was formed in 1913 to commence the manufacture of cartridge-powered captive bolt stunning equipment to become a world leader in humane animal killing. This resulted from a history of manufacturing and engineering by the Shelvoke's which include:
