I have a Probate Record listed with the UK PRO in the name of Maria KIMBER, dated 15 March 1847. The record indicates Maria Kimber was "...in the service of Mr. David RICHARDSON of No 1 Broadway Terrace near Douglas, Isle of Mann". I have attempted to determine where this address is located, but without success. Can anyone tell me if this is in fact a street address, or is it a farm/town/house??

Thank you for any assistance.
Pat
