Dave

Dave is the father of Jane Read and her siblings and the grandfather to their children, including Arthur, D.W., Kate and Cora.

Dave lives on the family farm near an unnamed town, which has been in the family for over 150 years. He plays as an independent, devoted and loving family man who enjoys playing checkers.

Personality
Dave seems to be loved by his whole family. He seems to be quite independent, hard-working, and traditional in views, to a point where he stays to have the Read family keep the house in good shape because it's been owned by them for over 150 years.

Dave is also a loving, devoted, very likable grandfather. He eventually gets the early stages of Alzheimer's in Grandpa Dave's Memory Album, when he starts to forget his grandson Arthur’s name.
