Sometime at the begining of the C19 Michael Danby and sons moved to Newcastle from Northallerton in Yorks. Once they got there most of them continued in the family butcher business. So far as I can gather this family seem to have been the only Danbys hanging around N-u-Tyne in the mid to late C19. If you have Danby links to either Northallerton or Newcastle my site is well worth checking out for overlaps in data. My cousins and I are developing quite a 'one-name' study on the Geordie Danbys and we'd love to hear from you.
