Granny and Slowpoke

[Pil]

Back in 1976, the Danish cartoonist Werner Wejp-Olsen started a series named Granny and Slowpoke. It wasn't a success in the States, but it became a big success here in Denmark.

I'm trying to find the American names for the supporting cast which is Granny's daughter (Sofie in Danish), her son-in-law (Soren in Danish), her grandchildren (Lise and Lars in Danish) and the family dog (Kurt in Danish).

Can anyone help me out here?
