Officially named The Wabash Presbyterian Cemetery, the cemetery is known locally simply as the Orio Cemetery. In 1833 Adam Shepard migrated from New Hampshire, and was deeded a quarter-section (160 acres) in the Orio area. Shepard and his wife gave two acres of land to be used as a church site and cemetery. In May, 1837, Elizabeth [Betsey] Bliss (the pastor's wife) died and was buried there.
In 1920, the first annual Orio Chowder was held for the purpose of providing funds for the upkeep of the cemetery. That tradition continues today. 2019 will be its 100th year.
The cemetery today contains over 950 documented burials. Documentation of the interments and pictures of the tombstones can be found on WabashGraves.com, along with all other Wabash County cemeteries.
