The Squires' residence was one of five involved in the Holiday Homes Tour this year.
Visitors paid for tickets, then browsed around in different homes to learn about architecture and family histories.
The Squires displayed family heirlooms, including a grandfather clock from the 1700's.
The family said aside from raising funds for the St. Joseph Symphony, the tour is a great showcase for the city.
"You can study architecture of almost any period here in St. Joe. It's a place that the world needs to discover. It is a fabulous city," Deedee Squire said.
Proceeds from the tour will help the symphony put on several concerts next year, including some for elementary school students.
