Wiltshire
Wiltshire was the territory of three Edwardian song collectors - Alfred Williams, Dr George Gardiner and Ralph Vaughan Williams (see vwml.org Archives). Henry Hammond also had a little success in Marlborough in 1908.
Not surprisingly, Cecil Sharp went elsewhere for inspiration and only visited Wiltshire in the last year of his life, collecting 2 songs at the Marlborough Union workhouse from 2 male singers. Their average age was 71. One was an agricultural labourer, the other's work not known.
