A good name for the estate of a fictional Scottish law lord castle?
I write a novel and one of my main character’s father is a senior judge. It can be a sequence of Lanarkshire, Ayrshire and Lothian. I have not decided on the specific location. Anyway, I’m on a suitable title for the estate and castle thinking .. It has its good and its not already there .. Please can someone help me? His name is John Lord Robertson. Such as (real) senior judges have had names such as Lord Mackay of Clash remote, Lord Mackay of Drumadoon .. Something could Gaelic or in relation to something low country .. I thought Drumdevan or Kinlochmoidart but both relate to the high country and it already exists. I also have a character of Lord Douglas MacDonald and he’s in the Highlands then give me the ideas for his successor screams. If I am good and my book is published, I’ll give you a shout on the list thanks! merci.PS: Thanks to all before responding. I did not choose my answers on time, so he went to vote.
