The Thoroughgood House was long thought to have been built by Adam Thoroughgood, an indentured servant who arrived in Virginia in 1622 and rose to prominence as a member of the House of Burgesses in Jamestown.  In reality the house was most likely built around 1719 or 1720 by Adam's great grandson, Argall Thoroughgood, on the Lynnhaven River in Virginia Beach.  Despite its small size, it was a brick structure built by someone of considerable means.  
This is the McDonald and Allison family tree descending from Adam Thoroughgood.  Adam may have been an indentured servant.  He  was granted a headright of 5,630 acres of land in the Virginia Beach area and became a prominent citizen and left property to his children.
