Searching Names In Text Strings

I receive a spreadsheet with over 400 lines of data every month. One row (J) contains information from companies with account details. The problem is that the info uses different formats, so the data strings within the cells can be quite long (sometimes over 100 characters, including spaces, dashes and slashes). The one identifier within each data string is a name, usually somewhere in the middle.

So for example a reference to JOHN SMITH might be "123456-01-smith/john-01/01/10-London-Edinburgh" or "2010-01-01-123456/SMITHJOHNMR/123456". I have a list of names (Column Y) and what I need is some way (probably VBA) for Excel to look down the list of references and compare them to the list of names, and if one of the names appears anywhere with in a text string, to put the name in column K. So if 4546/JohnSmith-01/08/13 or Leeds-London-123SmithJohn789 appears, put John Smith in column K, if 0123-MrFredBlogs-0321-5 appears, put Fred Bolggs in column K.
