Order against two columns at the same time (intersecting)

Question

I have a table with the fields CommonName and FirstName. Only either field has data, never both. Is there a way to order rows in an intersecting manner on SQL Server?

Example:

CommonName FirstName
Bern
           Wade
Ashley
Boris
           Ayana

I want records ordered like this:

CommonName FirstName
Ashley
           Ayana
Bern
Boris
           Wade

Is this possible, and if so, how?

Use a CASE statement to select the value for that row and ORDER BY that.

  CASE
    WHEN CommonName is null
    THEN FirstName

ORDER BY CommonName + FirstName, with appropriate ISNULL(<column>, '') if they are nullable.
