Byron's Birthplace

Can any of your correspondents give any information relative to the house in which Lord Byron was born? His biographers state that it was in Holles Street, but do not mention the number. [Our correspondent will find, on referring to Mr. Cunningham's *Handbook of London*, that "Byron was born at No. 24. Holles Street, and christened in the small parish church of St. Marylebone."]
