To the best of my knowledge this book is out of print. The author is deceased. A branch of this family does hold reunions every year and they may be able to help you. I believe it is in AL somewhere. If anyone does find a source for the book., please share it, as I have had a number of requests for copies. I do own a copy of this book and as my time allows will check and see if you family is listed in it. You might want to be aware of the limitations of the work. When Thomas and Margaret came to SC they brought a rather large family with them. The book only traces one line of that family forward for the most part. Recent DNA results are indicating that there are several other SC families closely related to them, however, the research is on-going as to exactly how. Those results can be found at http://blairsociety.org Several of the other children have been identified and a good deal is known and has been submitted to the BSGR about them. However, they are not covered in the book. I hope this helps. Charlotte Blair Stewart, Gen. Chair for the BSGR
