I also rename them after their jobs. Mr. and Mrs. Farmer, Mr. Build or Prof if I train them to be scientists...I try to keep track of the marriages in the beginning. I caught Mrs. Build one time in the middle of flirting with mr. Farmer...Put a stop to that flirtation, the moment I walked in on them! (Yes,the ocean worked fine). I also tried to ad sr. and jr. to names, in the beginning, but it seems there are limitations to the length of the name? Well...never mind, we'll work around that one.
