Anyone in cincinatti know this strain name?

My very old grandmother lives in cincinatti, whenever i go to visit she always has about an ounce of this weed that ive never seen anything like. First of all its very dense and does have the usual green weed color but a little darker. A 1g nug of this strain has about 4 or 5 seeds in it. The high is more of a sleepy one so it's more on the indica side. It doesnt smell that powerful and it tastes just like normal weed but more of a burnt taste. It's almost hard as a rock and very hard to grind. It also has a certain dry smell to it and whenever im in the city this is the strain I normally smell when someones smoking near me. If anyone lives in cincinatti and knows what this strain is could you enlighten me im very curious and cant find anything on this topic. Thanks.
