User blog:Darth Cenarius/What's the relationship does between Grand Moff Tarkin and Wilhuff Tarkin?

I oversaw the name Grand Moff Tarkin in LEGO Star Wars the Complete Saga in my DS. I'm curious what ties did Wilhuff have this guy. Could he be his son, his grandfather, his grandson, or his great great great great great great uncle's stepbrother's future son!?
