I take your point, but the people in Wigan at the time (and I think there is evidence of pre-Roman settlement of Wigan) would have considered themselves Brigantes. Just because you live in Wigan today doesn't mean you're less English than a Cockney.
I think it's an unusal choice but not wrong and trolls saying the Brigantes have named themselves after a tribe from a county, when that county (and England itself) didn't exist at the time are barking up the wrong tree!
