It can be done, but it's a lot of trouble. In such cases, I usually just use it as the profile for some real person with the same name and add a source. Most of the time, when I run into those, it's for some family I'm researching anyway, and I always have tons of people I can document that I'm not going to bother making a profile for. Like if I can't tell which Aloysius Bandersnatch this is supposed to be, I'll just make it into the first unprofiled Aloysius Bandersnatch I can find.
