This branch of the Gallimore family originated in Wirksworth, Derbyshire.  By the early nineteenth century, the Gallimores were involved in engineering (personal information courtesy of Marianne Morgan).  Gallimore & Co was a screw and hinge makers in Sheffield, until it disbanded in 1808.  The partners were John Gallimore, Josiah Gallimore, Paul Taylor, and Jonathan Marshall.  Its successor, J. & J. Gallimore, continued to manufacture screws in Bridge Street, under the brothers John Gallimore (d. 19 October 1840, aged 72) and Josiah Gallimore (d. 11 February 1824).  In 1821, this firm was dissolved.  

However, Josiah’s son, William Gallimore (1796-1860), continued the family’s engineering tradition.   According to The Ironmonger (12 May 1887), he founded his own firm in 1822.  William Gallimore appeared in directories between the 1830s and 1850s, first in Lambert Street, then in School Croft (a lane off Townhead Street, which once ran down the hill to Tenter Street).  William was listed as a manufacturer of German [nickel] silver goods and a dealer in skellit sheet and wire.  He was said to have been the second maker of German silver in the town.  William Gallimore, ‘German silversmith’ of School Croft, died on 23 May 1860, aged 65.  His burial in the General Cemetery was unconsecrated.  His wife, Elizabeth Gallimore, later worked independently in School Croft.  William’s son, also named William (see Wm Gallimore & Sons), became the driving force of a much larger business.
