The first settlers came to the area in 1860 when several farmers and ranchers moved to Rocky Creek, located three miles east of the community.

Hiram ("Hye") G. Brown and his parents settled in the Rocky Creek area of Blanco County, circa 1872.

The establishment of the post office drew other businesses to the area, eventually bringing in a grist mill, a blacksmith shop, and a cotton gin.

In 1965, on the porch of the Hye post office, Lyndon B. Johnson swore in Lawrence F. O'Brien as United States Postmaster General.

[3] In 1966, the Hye General Store and Post Office was designated a Recorded Texas Historic Landmark, marker number 2607.
