Mr Gentil said knowing the link has given him a lot more interest in listening to the Rolling Stones' songs.
"It's good to know we've got some fame in the family and some musical talent in the genes, not that I inherited any of it," he said.
After Whangarei District Council named the road in the new subdivision in the band's honour last month, Cr Brian McLachlan posted a letter to the rockers, asking them to jam at the street opening later this year.
Although his request remains unanswered, Cr McLachlan is still hopeful of a reply.
"The letter will be something I can hang on my wall one day if they ever write back," he said.
"I'm not giving up hope, I just haven't won the Lotto yet so haven't got the money to bribe them out here."
In June the Stones headlined the UK's Glastonbury Festival in front of up to 170,000 people - more than the entire population of Northland - and followed it with a show in London's Hyde Park to a crowd in the tens of thousands.
Cr McLachlan said if has no reply within the next month he will follow it up with an email, where he will be sure to include the Gentil's family ties.
Mrs Gentil said it would be quite amusing if the band did put in an appearance.
"I haven't really thought too hugely about it, as whether it happens or not is another story," she said.
