It’s a labor of love to mark the grave of someone who died more than two centuries ago, not to mention finding his burial place to begin with.

Lt. Joshua Treat would seem to be worth the effort, and come Saturday, July 19, the public is welcome to attend the dedication of the marker of the Penobscot River pioneer and Revolutionary War soldier at 11 a.m. at the old family cemetery in the Sandy Point section of Stockton Springs. The location is at the bottom of Devereaux Cove Road.

Fran Grant of Orono, Carol Gardner of Lincolnville Beach and Ruth Treat Kroll of Verona Island have carried out the project. Kroll’s family and Treat descendants helped Fran and Guy Grant install the tombstone.

The marker project has been supported by Penobscot Expedition Chapter, Daughters of the American Revolution, with approval for a plaque by the National Society DAR.

Treat, who was born Sept. 22, 1729 in Boston, was the great-grandson of Gov. Robert Treat of Connecticut. He is considered the first white settler on the Penobscot River.

He was both an armorer and an Indian interpreter at Fort Pownal, now Fort Point State Park, and took part in a conference with the Tarratines in 1759 in Hampden.

The Treat family, of course, was a part of the history of many communities along the Penobscot including Hampden, Bangor and Orono.

“The History of Penobscot County, Maine, with Illustrations and Biographical Sketches,” lists Robert, John, Joshua and Joseph Treat “from Frankfort” as having been in Orono by 1790.

Treat was married twice, to Catherine James and Mrs. Polly Lancaster, and he died on Aug. 12, 1802, in Prospect. It is believed that his first wife and some of his children are also buried in the family cemetery.

More than a dozen women throughout the country have joined the DAR over the years on lines back to Lt. Joshua Treat. His Revolutionary War service includes storing ammunition at his home after dismantling Fort Pownal.

After the dedication on Saturday, attendees are invited to bring a picnic to have at Fort Point State Park.
