DO NOT TRUST THIS BOOK for information regarding early migrations and connections among family lines. Ray had a tendency to believe that any families sharing a surname across the South must be related, and thus he placed people as sons where it appeared convenient. For example, he connected at least six southern Morrow families in various states to early Morrow immigrants to Virginia. DNA testing has since proven them all entirely unrelated. (For details, see The Morrow DNA Project)
This is not to say he did not do a tolerable job extracting vital records and on more recent lines or that he did not find grains of truth. Just be very cautious of claims of cross-state connections.
