He might have just turned 80 but super sleuth William 'Bill' Highfield won't be slowing down anytime soon.
Originally from England, Bill has been a volunteer, co-worker and friend to many at the family history library at The Church of Jesus Christ of Latter-day Saints in Nowra for more than 30 years.
While he's not a member of the church, Bill turns up every week to help anyone who walks through the doors wanting to connecting with their past.
The South Nowra resident has helped hundreds connect with their ancestors and personal histories over the the years.
Bill was recently thanked by friends and fellow volunteers, Judy Taylor and Dorothy Annetts.
"Bill's assistance is much sought-after as he is one of those people willing to take on projects at home to help those who can't use computers or are just stuck, and he goes above and beyond no matter what. It is rare for him to not find what he is looking for," Judy said.
"These words don't seem enough to express our gratitude for the opportunity to work with Bill and learn from him, and all the help he has given us putting us on the right track when we have strayed - and just being a friend."
Judy said many have voiced their appreciation for Bill's guidance and advice over the years, helping to find missing relatives and connect them to their family trees.
"We want Bill to know we appreciate all his efforts over the years that have led us to a firm friendship and continued love of family history, and we wish him well in his efforts to always help others," she said.
