Adding data as strings instead of new Qus & Ans?

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?
