As for getting a copy of the book, a lady in Florida along the same line had said there were newer versions printed, but it was a year or so ago and I do not have that info readily available. The name of the book is:
Governor Garrard, of Kentucky, His Descendants and Relatives by Anna Russell Des Cognets, published by James M. Byrnes, Lexington, KY, 1898.
My book is very old and needs rebound. I think there was another chapter added in the newer version by Louis des Cognets, Anna's son. You may be able to search the internet by the title and find it.I will try to find the info on where to get a copy, but it will take me a while.
