Charles,
I would not worry too much about the spelling off her name. You should just post as much information/guess work as you know about her, her husband and children (names, dates, places inc. date of immigration). These would indicate probable resources eg the 1881 census, that people may look up on your behalf.
Ideally you should find their marriage in England as it should be registered and it could confirm her name, fathers name and age. Try Freebmd.com
