Search Parts Of Columns Looking For Matches In Parts Of Other Columns In A Row

I have sheets with names of people in columns....some married...some not. When they are married, here's a sample format...

Jones, Donald T | Baker, Sarah Jane | Jones, Sarah Jane | Smith, Sarah J | Jones, Sarah Jane Smith

In this example, I would like to be able to determine which of the Sarah's belongs to Donald w/o having to visually look at each record ( 100,000's of records). (FYI: the names for Sarah would/could be her Maiden Name and possibly a name or two from a former marriage). What I need to be able to do is match and extract the names of Jones, Donald T and Jones, Sarah Jane and Jones, Sarah Jane Smith and eliminate Smith, Sarah J and Baker, Sarah Jane.

In my example, Donald is in the first column, but can be in any column on a row so the name positions are random across the columns. However, the format for each column is then same...Last Name, First Name Middle Name(or Initial) with a comma always after the last name in each column. The length of the last name also varies.

VBA or Formula that will search the cells in the columns of each row and return the names (complete contents of the cells with matching last names) that have a matching last name for that row.
