Re: book "Colemans of Mojack Bay"
I am fairly certain that the book, "The Coleman Family of Mobjack Bay, Virginia," by Sherrianne Coleman Nicol (1998) is currently out of print. It is available in a number of libraries, including the Library of Virginia (Richmond) and the LDS Family History Library (Salt Lake City). It is possible that you might be able to get access to the book (2 volumes) through inter-library loan.
I exchanged several e-mails with the author a little over a year ago and at that time she was working on a new version of the book, so, I would expect that you will be able to obtain an updated version of this family history sometime in the next couple of years.
