Same with settler maps: you can get this file http://rhye.civfanatics.net/civ4/RFGW/citynamesmap.rar and fill it with a civ you like. Replace -1 with the name of the city, surrounded by " ", Make sure you don't delete the " or the comma. The best way to fill these maps would be to apply the name of a city to a 2x2 box, when possible. There's room for random city list on the right. You can use RFC maps (included in the file) to help with city names in ancient languages.
