William Crathern [SEP] Introduction
William Crathern (14 February 1793 – 1861) was an organist and composer of sacred and secular music. He was baptised on 18 March 1793 at St Leonard's, Shoreditch, the son of Thomas Anthony Crathern and his wife Martha. He was organist at St Paul's Church, Deptford, and later served at St Magnus the Martyr in London, before taking up the post of organist of St Mary's Chapel, Hammersmith. St Mary's Chapel was a Church of England chapel, built in 1814, which became a parish church in its own right in 1836. The old church, on the corner of what is now Hammersmith Road and Edith Road, London W14, was destroyed by bombs on 16 July 1944.
