How many siblings did he have and what were there names ? thanks
James Boswell had two siblings who survived through infancy:
John Boswell (1743-1798), who became a lieutenant in the army, but who had to resign at the young age of 20-21 because of some sort of mental disorder which affected him for the rest of his life. See http://www.jamesboswell.info/biography/john-boswell-brother-great-biographer
David Boswell (1748-1826), who travelled to Valencia at a fairly young age to become a merchant, but later returned to England. See also http://www.jamesboswell.info/biography/thomas-david-boswell
He also had at least one other sibling, who died in infancy. The details escapes me just now, but I seem to recall that Alexander Boswell and his wife Euphemia (Boswell's parents) had a daughter named Veronica in 1741-1742 who died no more than 1-2 years old.

James Boswell died in 1795 believing he had touched and kissed a cache of Shakespeare's original letters and papers discovered by a Mr. Ireland. His friend, Edmond Malone, publicly exposed the lot as a forgery just a year later.
