Adding data as strings instead of new Q#s?

I have some data about parents and spouses for a batch of data I want to upload. I’m not sure if all the parents/spouses really merit their own wikidata item. I think I heard something in a training about the possibility of adding this information as a string (rather than as a Q#). Is this possible (I can’t figure out how to do it manually on wikidata)? If it is possible, is it a good idea?

I’m afraid I don’t know about this - my feeling is these are questions to ask of the Wikidata community (is it possible, is it a good idea), and then if the answer to both of these is yes we can see if it can be done directly from OpenRefine
