You can obtain a great deal of information and use it for sources (on the Munson's) by reading the 5 volumes of The Munson Record by Myron Munson. You can buy Volumes 3-5 from the Thomas Munson Foundation for $10.00 for all three volumes. Volume 1 and 2 I have on PDF, but I also was able to put these on the Foundation for members who could not get access to them. I did order and will receive from Walmart hard copies of volume 1 and 2. I hope this helps!! Good Luck.
