Looking for Information Regarding the Smith Family of Fisherton Salisbury Wiltshire UK

I am researching the large family of SMITHs who lived in Fisherton Street, Salisbury, Wiltshire, England - from around 1905 until at least the 1930's, where they ran a music shop known as 'Handel House'. Has anyone any knowledge of them please. They were associated by marriage to the HUMBY and MISSELBROOK families.
