What is the name of this kind of puzzle? It's driving me nuts!?

Ok, when I was in elementary school my teacher used to give out these puzzles that were like logical deduction grids. I hope I can explain it so that I can be understood. Anyway, there would be this grid with 6 or 8 peoples names and then a grid with details at the top. We then had little paragraphs about each person and then had to deduce from that little bit of information which person had glasses or which had red hair, or which had a grandma named Sue, etc. I'm just using these as examples of course. By the end of the puzzle, each person could only have 1 checkmark in the grid beside their name.

Does anyone know what I'm talking about? And if so, what are those puzzles called and where can I find some? Thanks so much for your help and I hope I was able to explain myself correctly.
