Fill in the 225 squares with top 5000 US surnames based on the categories in the top row and the first letter of the name given in the cell. For example, if you are looking at a cell with ‘C’ in its row, and ‘4 Letters’ in the column, that cell can be filled in with ‘Cook.’

Surnames not in the top 5000 will not be accepted.

Occasionally a cell may not have a qualifying answer, in which case it will appear blank and be a gimme.
