Grandfather Leicester played 113 matches for Southland and father Jason 143.
Gregor said it was "pretty special" to be named in the team.
He was very familiar with the team’s dressing room, having joined his father there many times.
"Growing up my whole life, I remember going along to Stag training, being in the change room after the game.
"Being around that environment when I was younger and then to get my own chance to be back in there myself as a part of that group and hopefully get on the field for them will be pretty cool."
It was probably something he took for granted as a boy, he said.
"Just thought that was normal."
Both his grandfather and father were very supportive.
He played flanker which was the same position as his grandfather.
The game had changed considerably since those days with flankers playing more like a back, Gregor said.
"All the stories I’ve heard from him, it definitely sounds like a completely different game, probably a lot more tougher, lots of fights."
At present he played for the Kaikorai club in Dunedin but when the provincial season started he would move to Invercargill.
Last week he turned out for Woodlands to help celebrate his father’s 300th game for the club.
He would need to balance playing rugby with his physiotherapy studies at the University of Otago, he said.
He was in his third year and was enjoying the subject. "It’s been good this year, lots of practical stuff, which has been pretty cool.
"It’s pretty cool learning about how the body works and how to look after yourself."
