William Henry Tayloe

William Henry Tayloe (January 29, 1799 — January 7, 1871) was an American plantation owner, horse breeder, businessman and land speculator during the first half of the 19th century. He inherited a vast estate from his father and expanded his holdings, pioneering new territory in the Canebrake region of Alabama.

Tayloe was born on January 29, 1799 at Mount Airy, Richmond County, Virginia, the grand colonial estate built by his grandfather Colonel John Tayloe II and then current residence of his father Colonel John Tayloe III, arguably the wealthiest plantation owner in the country. A year after William's birth his father built the The Octagon House in Washington, DC at the behest of George Washington. His maternal grandfather was Benjamin Ogle, ninth Governor of Maryland, and great-grandfather was former Provincial governor, Samuel Ogle.

After inheriting Mount Airy, Richmond County, Virginia from his father Colonel John Tayloe III, William, through his brother Henry Augustine Tayloe, began acquiring and speculating in land in the Canebrake, founding with his brothers Benjamin Ogle Tayloe and George Plater Tayloe, Faunsdale Plantation and co-owning Adventure Plantation, later part of Cuba Plantation.

After the Civil War Tayloe held the mortgage on Belair Mansion (Bowie, Maryland), the home of his brother-in-law Dr. George C Ogle, son of Benjamin Ogle II. The property was sold to the executors of the estate of the mortgage holder William H Tayloe, on May 16, 1871.
