A Civil War-era gravestone linked to the infamous Quantrill’s Raid has been discovered in a Kansas forest.

FOX4 News reports that Chad Gustin and his two elementary-school-aged children discovered two large headstones on land they own overlooking the Kansas River in Lecompton, Douglas County.

Historians believe that one of the two gravestones belongs to a man killed in Quantrill’s Raid, a bloody attack on the nearby town of Lawrence during the Civil War.

Quantrill’s Raid, also known as the Lawrence massacre, took place on Aug. 21, 1863, when Confederate guerrillas ransacked the Unionist town. Some 150 men and boys from the town were killed in the attack, according to the Kansas Historical Society, although some sources put the death toll higher.

One of the gravestones, which had been relocated from a previous gravesite, pays tribute to James O’Neill, a local man who was killed in the raid.

In a Facebook post, the Lecompton Historical Society notes that O’Neill was working on a bridge across the Kansas River Lawrence when he was killed. O’Neill was buried in an old pioneer cemetery that was destroyed 50 years ago, according to the Historical Society, and his headstone was moved to the area where Gustin and his children found it.

The other headstone pays tribute to a student from Lane University in Lecompton who drowned in 1877, according to the experts.

“The Lecompton Township, City of Lecompton and the Lecompton Historical Society have worked to relocate the [O’Neill] headstone, along with a headstone of a Lane University student who drowned in 1877, to the current cemetery of Maple Grove in Lecompton,” the Historical Society said in its Facebook post.

Civil War sites and artifacts from the era regularly offer fresh glimpses into the bloody conflict.

Earlier this year archaeologists in Delaware discovered the gravestone of a Civil War soldier that may provide a vital clue in uncovering a long-lost African-American cemetery.

Experts working at a property near Frankford, Sussex County, found the headstone bearing the name “C.S. Hall” and the details “Co. K, 32nd U.S.C.T.” This refers to Company K of the 32nd U.S. Colored Troops, which was a designation for African-American soldiers, according to Delaware’s Division of Historical and Cultural Affairs.

The site is known to the local community as containing the remains of African-Americans that lived in the area, officials say.

Other Civil War finds have also been made in recent years. Last year, for example, the remains of two Civil War soldiers were discovered in a surgeon’s burial pit at Manassas National Battlefield Park in Virginia. Also in 2018, a vacationer on a North Carolina beach captured drone footage of Civil War-era shipwreck.

In 2015, the remains of a Confederate warship were raised from the Savannah River in Georgia. The following year, the wreck of a large iron-hulled Civil War-era steamer was discovered off the coast of North Carolina. The ship, which was found off Oak Island, N.C, was tentatively identified as the blockade runner Agnes E. Fry.
