Probably a modern day receptionist or a parlour maid in the more recent years may be the equivalent of the good old traditional gillie employed by rich people in the past.
There are people who still engage gillies/ghillies when they go on fishing or hunting in the Scottish highlands.
It is fun to read names of businesses with ‘gillies’ in them but with different meanings, for instance, “Gillie Service” could be an office that supplies ‘gillies’ to anglers or hunters or it could be some other service provided by the owner with the first or last name ‘Gillie’.
