Wigan Genealogy

Hi People I am trying to trace one of my ancestors, Margaret Florence Henriettoo Hopkin, who was born in Ardrossen, Ayrshire around 1861. I traced her in the 1881 census where she was working in Runcorn, England as a domestic servant. She later married John T Frost and lived in Wigan, England. Has anybody got any information on her or her family? Thanks in advance Tony (Auckland, New Zealand)
