In The Homestuck Epilogues
Dad appears briefly
in Meat. As John is giving the teens some space for their reunion, a week before the meteors struck
on John's birthday, he sees Dad through the window of his study. Dad is smoking a pipe and listening to his favorite jazz music. There's a kitchen timer set up on his desk. His window is slightly open, but he doesn't seem to notice John, and John soon walks away. The timer goes off just as John is using his retcon powers to zap away with the other kids.

Skaianet Systems Incorporated files
The files reveal that pre-scratch Dad's biological father is Stan Laurel, though later his mom married and he got a stepfather with the surname Egbert. Since Laurel died in 1965, this would make Dad at least 44 years old when Homestuck began. In the post-scratch timeline, John Crocker's wife is covertly impregnated with Dad's pre-scratch self to be post-scratch Jane's father.
