The Baptist Church in Hastings - and indeed, it may be said, the town generally, suffered great loss by the death of the Rev. William Barker, for many years Pastor of the Wellington Square Chapel. He was born at Olney, Buckinhamshire, and wa educated in early life for the ministry. He preached his first sermon when only fifteen years old, and commenced the work in which he was so successful in after years at Walsall, Staffordshire, as an Independent. However, in the year in which he was married, his religious views underwent a change, and he was received into the Baptist Church, a member of which he remained until his death. It was in August, 1863, that he came to minister to the Wellington Square congregation. He died in 1891, in Devonshire, at the age of 67 years. He was an extremely able preacher, and was held in deep respect by all.
