Don't know whether you have contacted NT Archuves, but they have some info on your line, includung photos. I wrote to them as I thought what they had might be my Lampe family.My lot orininated in Bremen 1550's. Branches went to different places - mine to Danzig via Konigsberg. Mine came to Vic1852 and one branch went to SA. As far as I know no Lampes of that branch still there.
