As per my reply #3, I still think that if you obtained Ann's 1881 marriage certificate it might provide useful clues. Apart from anything else, you could search the 1881 census on an "address search" basis (for the address given for each party upon marriage). Sometimes an address search finds people who are otherwise untraceable because their name has been mistranscribed, or the index is otherwise unsatisfactory. Witness names are potentially also very useful, not to mention finding out what information the bridegroom gave about himself/his father.
