Conor, An illustration of your data might help. For now, I assume that your data started out something like this, where origob is the original observation number for each group of names, newid is the new observation number, and X and Y are some other variables: origob names X Y 1 "Alex Charles Henry" 123 456 2 "Mary Liz" 789 324 And now looks something like this: origob newid names X Y 1 1 "Alex Charles Henry" 123 456 1 2 "Alex Charles Henry" 123 456 1 3 "Alex Charles Henry" 123 456 2 1 "Mary Liz" 789 324 2 2 "Mary Liz" 789 324 And you want this: origob newid names name X Y 1 1 "Alex Charles Henry" "Alex" 123 456 1 2 "Alex Charles Henry" "Charles" 123 456 1 3 "Alex Charles Henry" "Henry" 123 456 2 1 "Mary Liz" "Mary" 789 324 2 2 "Mary Liz" "Liz" 789 324 If this is right, you can go from the second stage to the third stage by doing the following: bysort origob: gen name = word(names, _n) Hope this helps.

However, I want to look at the relationship across each individual, so I am trying to separate the names. What I have done: expanded the observations based on how many individuals are in each observation's string variable. Labeled the duplicate observations 1, 2, 3, etc. What I need now, is a command that will take the number in my duplicates and take the corresponding individual's name with respect to its position in the string variable, separated by a comma. Any insight would be helpful.
