The three-story Hotel Union first appears in Sanborn fire insurance maps of Wilson in 1908. The wooden building had two storefronts on the ground floor and accommodations above.
The hotel also appears in the 1913 Sanborn map. By 1922, however, the Hotel Union was a boarding house. Its ground floor had been expanded to add another commercial space, and the one-story extension on the back of the building comprised a separate dwelling. In the 1922 Wilson city directory, Gertrude Adams is listed as the proprietor of the Lynnhaven Hotel, and the 1925 directory shows the Whitley Hotel at 535-537 East Nash. Maggie A. Whitley was proprietor. In the 1928 directory, the address of the Whitley is 541 East Nash. The hotel is visible in a postcard of East Nash Street circulated in the 1920s.
In January 1928, a fire broke out in a second-floor bedroom of the Whitley. Quick action by the fire department prevented extensive damage.
Wilson Daily Times, 5 January 1928.
The 1941 edition of The Negro Motorist Green Book lists the Wilson Biltmore at 541 East Nash Street, which appears to be a later iteration of Hotel Union/Whitley Hotel. (This observation matches Samuel C. Lathan‘s recollection.) The building burned to the ground in the late 1940s.
