In my research for Hatfield I have discovered that my line goes back to the spelling of Hetfield. Moses Hetfield of Orange County, NY, (served in the Revolutionary War) had sons, one named Adonijah. Thus far I believe that Adonijah was my ggg grandfather. Adonijah and some of his sons migrated to Ogle County, Illinois, but his son David (my gg grandfather) and another son migrated to Northmoreland,PA about the same time. Those who moved to PA exhibit a name change to Hatfield in the records, but Adonijah and sons in Illinois kept the spelling Hetfield. I still have a lot of proofs to do, but from records I have thus far gathered, I am pretty sure I am on the right track. Will be happy to share any info I have.
