Yes, the booklet starts out with the origin of the name. I went back & rechecked my copy to see if there was any identifying information--even which library that it came from & found none. The book only deals with the French origin of the family & mentions immigrants to the U.S. but does not trace the family further--stops with immigrants in 1600s. In other words, this booklet does not prove the descent of the DEFORD family of today from those immigrants mentioned. Now, some or all of the immigrants cited did exist, but our research to date (I've researched this line at least 20 years & other researchers are working on this line also) does not prove the descent of Maryland DEFORDs from the individuals mentioned in the booklet. In fact, most DEFORDs from Maryland appear to be descended from a Lewis DEFORD who was naturalized in the 1700s & settled in Queen Anne's County, MD. Lewis was not mentioned in the booklet. By the way, a fellow researcher informs me that the Newberry Library copy is filed under "DEFORT," rather than "DEFORD."
