  ESSOLF (ASSOLF) of TONG THORNHILL on the CALDER, YORKSHIRE d. AFTER
  1189
  m. ? m. ?
  By the 12th Cent. Essolf was one of the most important local
  landowners. His extensive holdings suggest that he had considerable
  success at trading and investing. Iron was starting to be used in
  farming implements & instruments of war, so he may have invested in
  ironstone workings. His Grandsons bequeathed such workings in
  Shitlington & Flockton to Rievaulx Abbey. It is recorded that he had a
  large number of sons, amongst whom his holdings were eventually
  divided. Some of these sons appear to have been very capable men.
  
  Essolf was the first to take on a second name (which became compulsary
  under Norman law about 1100AD).
