Hi ,William Lundberg was a silversmith and trader operating between Dublin and Bristol from 1840 and onward.William married a Mary Dwyer from Ireland and the couple had several children.Tragedy struck and it seems the family was split for some reason .I wonder if anyone recognizes the Lundberg name in the Bristol area census records(sometimes spelt Lumberg,Lumdberg,Laveburgh,Lundbirg etc).Best wishes,Doughy.
