An option to do this is to quit all the conflictive's letters and make a match by the result of quit all that conflictive letters from the source and the query.

Once you do this can make a list of all the possibilities.

For Example if you want to parse Connecticut will be like

Query
Conecticut --> Coecticut

Source
Connecticut --> Coecticut

But be sure to select the right conflictive letters to discriminate. And I'll do the same to the repetitive letters like "nn" in Connecticut or "ss" and "pp" in Mississippi.
