Hello - I am related to a Merritt family that lived in what was then Harper's Ferry, Virginia in the early 1800's (very close to Frederick, MD. I haven't been able to conclusively connect this to the New Castle, DE Merritts but I think there is some relation there, migrating to Frederick-Harpers Ferry via Lancaster, PA with german immigrants. The family that I'm descended from split up - some moved to Cabel County West Virginia (on the Kentucky boarder) and my line moved to the Baltimore area in the late 1800s. I've also found a Merritt family in Cecil County, MD (again, not far from New Castle, DE). I haven't conclusively made a connection there, either.
