Mike,
it's possible your grandparent's kin met my maternal grandfather's; the Longhope Wrights (and their Mitcheldean/Cinderford cousins) all originated in the Cowley/Brimpsfield area c1800, and before that Compton Abdale c1700, a mile or two from Chedworth.
Does this mean you might even have a hint of Roman in your DNA ?..
