The Acklam (or Acklom) family were Lords of the Manor of Hornsea, living at the Old Hall on Southgate, and were Quakers. They were friendly with the Harrisons, also Quakers. I can find bits of information about the Acklams but there don't appear to be any records of the Quakers in the Hornsea area (or I can't find them!) and no mention of the Harrisons. If anyone has any snippet of information on the subject, I'd be grateful.
