The phrase Uncle Tom Cobley and all is used in British English as a humorous or whimsical way of saying et al., often to express exasperation at the large number of people in a list. The phrase comes from a Devon folk song "Widecombe Fair", collected by Sabine Baring-Gould. Its chorus ends with a long list of people: "Bill Brewer, Jan Stewer, Peter Gurney, Peter Davy, Dan'l Whiddon, Harry Hawke, Old Uncle Tom Cobley and all." The surname is spelt as "Cobleigh" in some references.
Whether Tom Cobley, or the other characters from the song, ever existed is uncertain. Local historians have attempted to trace them in and around Dartmoor (for if they did ride to the fair at Widecombe, they may have travelled some distance).
There is some suggestion that his relatives have been traced to a family which had moved to Plymouth in the early 1900s, but that no longer hold the name Cobley.
The strongest claim is held by the village of Spreyton, to the north of the moor, whose churchyard does indeed contain the grave of a Tom Cobley, buried 11 January 1844. However this is said to be the grave of the nephew of the 'real' Tom Cobley, who died in 1794 and whose grave is unmarked. Cobley disapproved of his nephew and kept him out of his will (signed at Pascoe house, Colebrooke). The house at Butsford Barton, Colebrooke, was supposed to have been the home of Uncle Tom Cobley.
