The 1836 ed. is slightly different and enlarged than the 1st ed. of 1825. 98% of its contents are lifted from "Missiouri Harmony" and "Kentucky Harmony." There are about 3 pieces unique to the book. The compiler was a baptist from Miami County, whose father came to Ohio from Pennsylvania. In terms of its influence on the "Sacred Harp," it's kind of convoluted. Houser, who had family in Kentucky, evidently acquired a copy of this book. Houser then printed the few unique pieces to Knight's book in "The Hesperian Harp," including HAMILTON, OHIO, and CINCINNATI. However, with the exception of HAMILTON, none of the others are the earliest, nor the direct versions of the folk hymns in the Southern shape-note repertory.

So to make a long story short, Knight versions of his tunes only appeared in one Southern souce, Houser. However, the tune families had been circulating through the different tune regions of the U.S. Knight's is usually one of the earliest sources, but not the earliest, and not particularly influential on other compilers.
