I have a full text indexed column in SQL Server 2008 which has the following rows:
W Smithers, Wilda Smithers, W2 Smithers
When
The W probably is a stop word. Try to remove it from the stoplist.
Check this link to see how it is done: Configure and Manage Stopwords and Stoplists for Full-Text Search
EDIT
Try to recreate the FT index, but this time do not specify any stop list at all.
