Waiting for mail

I am waiting for a letter from the Scottish Genealogy Society in Edinburgh, Scotland. I found a reference to Catherine Fisher, wife of Hugh Forgey, in Donald Whyte's  A dictionary of Scottish emigrants to the USA. A book I found at Google books. The author deposited his source material at the Scottish Genealogy Society library. I requested a copy of the source material for Catherine Fisher and her father Archibald Fisher. I am hoping it contains leads to more info. I am still searching for a record of the marriage of Hugh Forgey and Catherine Fisher, and a list of the names of their children. They lived in Hawkins County and Knox County, TN in the late 1700's and early 1800's.
