Hello again,
As I said, you've probably found everything there is to find but I must ask whether you have read;
MEMOIRS OF A HIGHLAND LADY
THE AUTOBIOGRAPHY OF ELIZABETH GRANT OF ROTHIEMURCHUS
AFTERWARDS MRS. SMITH OF BALTIBOYS
1797-1830
http://www.scottishcorpus.ac.uk/cmsw/search/document.php?documentid=76
It's full of anecdotes about George William Gillio's wife and daughter Amelia, who sounds like a right one!!!, and son George, who wasn't much better.
I wonder whether Mrs Smith was related to Martha Elizabeth Smith, JF Wright's wife.
BTW, may I ask which of Edward Lambert's children was your Great Grandparent?
James.
