Thank you snowqueen, that's brilliant, a breakthrough with my tree. Much appreciated.
Sandymc, that Alexander Stephenson you found in the census living with daughter Mary Ann, is my great x 3 grandfather. I have been researching this for quite some time and am convinced that Alexander who married Kitty Hartley is either a cousin or uncle of his. Have all the same family names and occupations.
Will plod on, many thanks.
