On December 15, 1859, C. L. Jones, conveyed to the Masonic Lodge, lots two and three in Block "S". A Lodge Hall was erected with the lower room of the two-story building being used as a schoolroom, and the top floor used by the Masons. According to Judge Heath, the laying of the cornerstone of the building brought a large crowd to Rockwall. The building was torn down in 1878.
Another two-story building was soon erected at this same location, and lodge owned and continued to use the upper story at least from 1885 until 1955 when it was sold. The Lodge then purchased the adjacent one story building and continues to use that place to meet.
East Trinity Lodge obtained it's charter on January 18, 1855. The committee on work and returns had reported on January 17, to the Grand Lodge that:
"East Trinity Lodge, U. D. work correct. Returns corrected. We recommend that a Charter be issued on payment of fees."
Sterling R. Barnes was the first Junior Warden of the Lodge. When he moved his family to the area in 1844, from Holly Spring, Mississippi, he carried with him a Demit from the Holly Springs Lodge No. 35 - AF & AM, and that Demit continues to hang above the station of the Junior Warden.

John O. Heath had an interest in a mercantile store in Rockwall and still lived in the vicinity, but for some reason, perhaps an oversight, was not listed amount the 1857 members of East Trinity Lodge. Heath's farm was near Willow Springs. The Post Office was in J. O. Heath's home and was called "Black Hill."
