I am researching the Brettargh/Sidgreaves Family from Sefton, Lancashire
Henry Brettargh married Mary Sidgreaves in 1808 and had seven children, Robert, Mary, Anne, Jane, Helena (married Thomas Grimshawe) Henry, (Father Henry Brettargh of Dodding Green)James and Elizabeth
I would be pleased to hear from anyone with connections, Henry and Mary were my Great,Great Grandparents
