ARLINGTON, Va. (AP) — For more than 100 years, the cremated remains of two brothers — Civil War soldiers from Indiana — sat on a funeral home shelf, unclaimed and largely forgotten.

On Thursday, their remains were given a final resting place at Arlington National Cemetery, which dedicated a new columbarium court designed to hold the cremated remains of more than 20,000 eligible service members and family.

It is the ninth columbarium court at Arlington, where roughly 400,000 are interred.

The first six remains to be interred at the court were recovered by the Missing In America Project, an organization based in Grants Pass, Ore., that scours funeral homes across the country to recover remains of veterans that have gone unclaimed.

Since 2006, the project has visited nearly 2,800 funeral homes and found more than 2,000 cremated remains of veterans, including six Civil War veterans. The group researches the names of anyone who could be a potential veteran, and if they find one, they organize a burial service, usually at the nearest VA cemetery, where veterans are entitled to a free burial.

In Indiana, the group’s work uncovered brothers Zuinglius and Lycurgus McCormack, whose ashes had sat on the shelves of a funeral home since their deaths in 1912 and 1908, respectively.
