Henry Riley writes in his Memorials of the inscription on the coffin of Godefrey le Trompour and of trumpeters generally that: The persons who followed this trade mostly lived, in all probability, in Trump Street, formerly Trump Alley (a much longer street then than it now is), near the Guildhall; their principal customers not improbably being the City waits, or watchmen; each of whom was provided with a trumpet, also known as a "wait," for sounding the hours of the watch, and giving the alarm.
In Trump Alley, close adjoining, he probably lived, sold trumpets, and died;—if we may judge from the character of the writing, in the latter half of the 14th century.
[6] Trump Street was recorded by the cartographer John Rocque in 1746,[6] and The London Encyclopaedia write that it "probably derived from a nearby Tavern, the Trumpeter Inn".
[8] It appears on Richard Horwood's original (1799) and revised (1813) map of London with Honey Lane Market at its western end where Russia Row is now.
[9] A tavern known as Blossom's Inn once stood on the north side of the street on a large site on the corner with Lawrence Lane from the fourteenth century until 1855.
