No
Billy's father is not mentioned. Billy's grandfather was Ephraim Black, a former elder of the Quileute tribe. He inherited Ephraim's place on the tribal council and knows the tales of the origins of the Quileutes. Because there were no vampires around at the time, he did not become a werewolf. Billy Black is the human father of Jacob Black, Rachel Black, and Rebecca Black. source: http://twilightsaga.wikia.com/wiki/Billy_Black There has been some speculation among fans that Billy Black is really Ephraim. Stephenie Meyer, however, has said that Billy really is Ephraim's grandson. source: http://twilightsaga.wikia.com/wiki/Ephraim_Black

Fictional
He could have been, but no vampires lived in Forks at that time, so he missed the boat, and when they came back he was too old. It is unknown if Jacob's grandfather was a wolf, but his great-grandfather was Ephraim Black, so definitely a werewolf.
