Hezekiah Alexander was born January 13, 1722, in Cecil County, Maryland. He was the son of James Alexander and Margaret McKnitt. His grandfather, Joseph Alexander, had emigrated to Maryland in the early years of the eighteenth century. Sometime after 1754, Hezekiah, as well as his brother, John McKnitt, emigrated to North Carolina.
The Alexanders quickly established themselves in their new home, Mecklenburg County. Although Hezekiah had come to North Carolina as a blacksmith, it was as a farmer that he made his fortune. On April 1, 1767, he purchased, from his brother John, a tract of land containing over three hundred acres located on a branch of Sugar Creek. It was here that in 1774 he built a stone house to accommodate his wife, Mary Sample, and their growing family. The house was to remain Hezekiah's residence until his death in 1801, and became the center of his expanding farming enterprises. Both Hezekiah and John McKnitt Alexander were active in the affairs of their county. John was a crown surveyor and county magistrate. Hezekiah played an active role in the church, being an elder in theĀ Sugaw Creek Presbyterian Church. He was also a trustee of Queens College, chartered in 1771, renamed Liberty Hall in 1774. Both brothers numbered among their friends and associates the prominent community leaders of Mecklenburg; among these were Thomas Polk, William Sample, Ephraim Brevard, the Phifers, the Averys, and Jeremiah MaCafforty.
With the approach of the Revolution, both of the Alexander brothers became increasingly involved in the events which would culminate in independence from Great Britain. In 1775 both men were members of the Mecklenburg County Committee of Safety. On August 21, 1775, Hezekiah was appointed by the Provincial Congress meeting in Hillsborough to the Salisbury District Committee of Safety which was to serve as the local governing body for a multi-county area. In November, 1776, Hezekiah joined other state delegates at Halifax to form the Fifth Provincial Congress which was charged with the task of writing the first state constitution. After the Halifax Congress, Hezekiah joined the Fourth Regiment of North Carolina Troops as Paymaster.
Hezekiah Alexander's stone house is possibly the only extant structure belonging to a framer of the state's first constitution.
Architecturally, the Hezekiah Alexander House reflects the influence of the German emigrants who came to North Carolina from Pennsylvania in the 1750s and 60s. During that period several thousand families settled in Mecklenburg and the adjoining counties. Many of those settlers constructed houses of native stone similar to that of Alexander's. They were quite similar in form to houses built by the Germans in Pennsylvania and the Dutch in the Hudson Valley. The Hezekiah Alexander House is one of the few surviving examples of this architectural type in North Carolina.
