I'm afraid I can't help. My paternal ancester migrated to Ireland in the 1690's and there married and later died about 1724. That same year his widow and her sons and daughter migrated to this country, initially settling in PA and later migrating on to the Shenandoah Valley. There was no Robert among the sons who migrated in the family from Irelandimmigrants. The first Robert in my direct line was born in 1818.
Wish we could have matched family lines.
