A lot of women these days take their new husband's last name and keep their maiden name, seperated by a hyphen (ie Mary Smith-Barney). What happen's when Mary Smith-Barney's son (Jim Smith-Barney) marries Julia Sweeney-Todd's daughter Sandy Sweeney Todd. Is Sandy's last name now Sandy Sweeney-Todd-Smith-Barney, or some derivation of these names?
