Another brother Corbin Griffin (d.1813) received a medical degree from the University of Edinburgh before setting up a practice in Yorktown and became chief surgeon during the Revolutionary War before his imprisonment by the British, and later served as a Virginia state senator.

They had only one child, Elizabeth Corbin Griffin Stewart (1779-1853), who survived two husbands (including a Williamsburg physician) and ultimately died in Philadelphia.

Thus, Griffin led about 900 militia and Virginia regulars into Mount Holly, from which he harassed the pickets of Colonel Carl von Donop at Bordentown.

Colonel Von Donop brought all of his 2,000 or so troops to Mount Holly to punish Griffin in the Battle of Iron Works Hill.

During this period, Williamsburg remained strategically important as the colonial capitol and was threatened by British warships offshore in Hampton Roads.
