Over the nearly 40 years I have been involved in our family research, I have discovered more than 1000 documents and a few books.  There is a book written in 1950 by May & Torrance McHenry. Over the years since it was written, many new discoveries have been made and some of the data has been updated. Regardless, it is the best history book on our family that I have found to date.

You can access it here: 

The PDF file below is comprised of 117 pages, so it's not something you are going to read in a day, but if you are related to the McHenry's then this is where you should start. It begins with my father Floyd W. McHenry (1925 - 1969) and goes back in time to the mid to late 1500's to Henry McHenry.

Our Family Tree is Ancestorial in that it begins with my Father, Floyd McHenry, and goes back in time reaching the 1500's.

Happy History Hunting . . .
