Thora Read

Thora Read, commonly known as Grandma Thora, is the mother of David Read and his siblings as well as the grandmother to their children, including Arthur, D.W., and Kate.

Personality
She is shown to be very kind, supportive, and understanding, but is also a poor cook. She loves bingo and is best friends with Mrs. MacGrady, lunch lady for Lakewood Elementary. She sometimes babysits her grandkids such as on New Year's Eve, when she allowed D.W. to stay up until midnight not knowing that D.W.'s parents already told her that she couldn't. She's also very good at playing marbles and gives Arthur some lessons on how to play the game well. In Family Fortune, she goes to an antique show with two of her grandchildren.

She has a prized doll named Clarissa (shown in Clarissa is Cracked). In the same episode, it is revealed that she has three older brothers. She also takes in a stray dog named Killer that was found on her porch. It's never been revealed who her husband (the father of David and his siblings and the paternal grandfather of Arthur and his sisters), as he's never been seen or mentioned--it's likely that Thora's either widowed or divorced.
