This question is definitely not a duplicate! The question deals with the problem of recording the details about persons that we might be interested in, but before we know we are interested in him or her. I would suggest the OP edit the question to make this clear.
If the information is about a person, the easiest way to handle it with most current software is to simply create a new person record with only the new information and do not link that person record to any other existing persons or families. You will still be able to find that record when you search, so the information will not be lost. Later, when you learn enough to know who the person really is, you can either merge the record with an existing person record or just get rid of it.
This is getting precariously close to the whole topic of how do you transition from the "person-oriented" genealogy that we all do when we are beginners, to the "record-oriented" genealogy we must learn to embrace once we are dealing with generations way beyond living memory. Your question is really the very, very critical question of "how do I store my evidence before I really know what it means?"
I wanted to tell you to "create a new persona" for the information, but that's another topic that should be explored separately.
