There are many articles who do a much better job explaining the importance of the United States Colored Infantry and who made up the troops. The troops were made up freed men from the North and South. For Southern ones, many volunteered to fight after a Southern city was under control of Union troops. They played an important role in defeating the Confederacy.
Listed on the National Register of Historic Places, here is info from the application which gives a good history of this praise house and the overall purpose of praise houses.
“The Mary Jenkins Community Praise House, built ca. 1900, is one of four known extant praise houses on St. Helena Island [one has since been removed – today there are only three praise houses on St. Helena Island]. Praise houses were first established on St. Helena plantations in the antebellum period, as slaves used small frame houses or other buildings as places to meet and worship. After they became freedmen, they built praise houses on or near the old plantation, in most instances calling their community by the name of the former plantation or plantation owner. Although the extant praise houses date from ca. 1900, their function has persisted since before emancipation and the basic architectural form has been retained. Since there were, and are, few formal church buildings on St. Helena, most islanders could only walk or ride to the main church on Sunday morning. For other community meetings or services, praise houses were built in each of the communities created by the former plantations, and services were held on Sunday, Tuesday, And Thursday nights, as well as the Watch Night Service each New Year’s. A typical service might consist of singing, prayer, perhaps a member’s testimony of a religious experience, and almost always ending with a “shout.” Kit Chaplin built this praise house ca. 1900; Paris Capers, born in 1863, was one of the early elders. Members of Ebenezer Baptist Church still attend services here today; a cow bell, which is still in the praise house, has been rung for many years to alert the members to a service or meeting.”
Coffin Point Community Praise House. The roots of praise or “prays” houses are tied to enslaved people building small places of worship on or near the plantation where they labored. They were kept small because enslavers feared large gatherings. (If you look at police response towards Black Lives Matter protests and the insurrectionists, then you know that fear continues today.) This praise house was built in 1900 and rebuilt in 1950. It is still used occasionally by the Coffin Point community.
Talbird/Tabor/Talbot Cemetery is the largest Gullah cemetery on Hilton Head Island. On one side are condos and the other is Skull Creek. The cemetery’s founding is in the 1800s, but the exact date is not known. The Mount Calvary Missionary Baptist Church tends to the cemetery that experienced significant damage during Hurricane Matthew.
