Whiteout - your find certainly matches that 1841 census record - I think you may have found her ..hopefully

BUT - George Henry Grimshaw's birth registration - Ashton & Oldham - March quarter 1839 - gives mmn as Ogden.

That is why I asked OP for details of children and whether they were still here for the census so we did not spend time looking for them if they had left England before June 1841

just thought we might find them in Crumspall in 1841 census as they didn't leave until August - but Kay99 has found them on the Arrivals list
