The same person may have submitted the information or it may be two people working the same family line.
spelling may be another problem - it would be good to be in touch with someone in Scotland to verify the spelling: Henlocklaugh or Kenlochlaich - I find all kinds of spelling errors in genealogy of towns, areas, lakes, etc.
