Why did James Boswell move his family from Scotland to London in 1786?

In 1786, James Boswell moved his family from Scotland to London primarily because he had been called to the English bar from the Inner Temple and held the belief that he could achieve greater professional success practicing law in England than he had in Scotland.12

Additionally, Boswell felt that residing in London was essential for him to complete his major work, The Life of Samuel Johnson, LL.D., and to remain available to the earl of Lonsdale, who had provided him with encouragement and secured his election as recorder of Carlisle. Despite these motivations, the move proved difficult; Boswell had little legal practice in London, and his wife, who suffered from tuberculosis, pined for their home at Auchinleck.12
