A woman selling her parents’ Rockville Centre home recently uncovered a treasure trove from the 1800s in her attic.

Sharon Stack discovered some incredible photographs and keepsakes in the floorboards of the house she grew up in.

“I looked down into the gap and started pulling them out. I said, ‘Oh my gosh, this has to belong to the first owners of the house,’” said Stack.

The house on South Forest Avenue in Rockville Centre was built in 1923. Stack and her mother moved into the home in 1961. She says they bought the house form the original owners, Andrew Robert Fritz and his wife Elsa.

Some of the photography are tintypes, while others are sepia. The pictures were taken in both Germany and by a photographer in New York.

“They are the history of the family. Things that were saved carefully, brought over on a boat originally and passed down to the next generation,” said Stack.

Since discovering the pictures, Sharon has been trying to find their rightful owners. She's posted on Facebook and has researched the Fritz family online.

Stack says Andrew Robert Fritz was an architect and designed Oceanside High School.

So far, she has not had any luck contacting any extended members of the family. If you have any information on the Fritz family, you can contact Sharon at fritzheirs@gmx.com.
