I have two books pertaining to these two families...

Hatfield and Phillips Familes of Eastern Kentucky and Southwestern West Virginia by H.L. Sellards,Jr.-This is written in genealogical form

The Feud:The Hatfields and McCoys The True Story by Dean King-Includes selective genealogies of both Familes,pictures,and accounts of descendants,casualty lists and maps

Just thought I'd post these for anyone who is doing research on the feud or certain people within the families.
