On December 11, 1725, founding father George Mason IV was born in a plantation within the Mattawoman Country Estate in Dogue’s Neck, Virginia, within Mason Neck, in Fairfax County. George Mason IV grew up in a plantation that his father George Mason III owned next to the property of Colonel William Eilbeck.
George Mason IV’s father died when he was ten years of age and he inherited the hundreds of acres of land his father owned. William Mason, one of George Mason’s sons, inherited the lands between Chicamuxen Creek and Mattawoman Creek to his son William Mason. In 1780, Mason IV’s eldest son George Mason V, at the age of 23, inherited Mattawoman from his maternal grandmother, Sarah Eilbeck.
