The person your forbear (Mary Drever his sister) moved to live with was my Gt. Grandfather Thomas Drever from Lingro Shapinsay. I have contact with the Shearer side. He was a Manager of a yeast and egg company called Mawson swan and carter and lived in Matamba Terrace.. He was also Alderman in Sunderland. I have a comprehensive collection of Drever family tree including the Shearer side.
