We don't have any Davids in our line of the family but there is a David noted in the Caldwell/Morton line of the family. Drs. David and Daniel wrote/collaborated on a volume of their research on the Morton family. They were from Missouri and have noted in their book that there are only 3 volumes printed. One is in the library of Congress in Washington, the second in the Newberry Library at Chicago, ILL and the third in the Public Library in Kansas. All of their information is not absolutely correct but it is accepted as THE volume on the family. You might like to research them at one of these facilities since they cannot be checked out of the library. Good searching. Peggy Fountain Taylor
