Claire Tanner is Danny's mother and the paternal grandmother of the girls. She was the one who was there for Danny in the first few months after Danny's wife, Pam died, temporarily living in the house with them. She helped Danny care for the girls. The day she moved out was the day that Jesse and Joey moved in. She is also divorced.
She came back in the episode, "The Return of Grandma", so she could check up on Danny, Jesse, and Joey to see how they were doing with the girls. To her surprise, the place was a mess. Jesse and Joey expected her to clean the whole house since she was there, and went out to catch a movie. When they came back, Danny informed them about what Claire said—that she wanted them to clean up their mess. She brought in Jesse and Joey's mothers, Mindy Gladstone and Irene Katsopolis. They offered to move in, which seemed more like a threat to the guys. She, Mindy, and Irene made a deal with Danny, Joey, and Jesse—if all three guys could clean up the house in a few hours' time, they would not move in. If they failed in cleaning the house in a few hours, they could move in. Claire and the others were surprised to see the house so clean after a few hours, and then didn't move in.
In the episode, "The Miracle of Thanksgiving", it was revealed she lived in Tacoma, Washington, after Danny told Jesse and Joey that Claire was getting snowed in, so she couldn't cook a special Thanksgiving dinner for Danny, Jesse, Joey, and the girls.
Finally, in season three, "Granny Tanny", Claire returned to the Tanner household for a visit. After being given a paint set, a gift from the family, she became sad because it reminded her that she was retired now. The whole family decided to make it seem like they needed her so she would be happier. And it worked, resulting in her wanting to move in with the Tanners and get Jesse and Joey to move out. Eventually, Danny told her that they were just acting to try and make her feel better, and said that even though the girls didn't need her in the house, she could still be in the neighborhood.
It was believed that Claire moved from Tacoma, Washington down to San Francisco, California.
