Josiah Dunn was a resident of Wilkes County, Georgia, born in about 1735. He was a member of the Quaker Settlement at Wrightsborough until 1775 when he was banished from the group for "using profane language" and hiding a thief. During the American Revolution, Dunn served as a captain in the Wilkes County Regiment of the Georgia Militia and was eventually promoted to colonel of the Richmond County Battalion later in the war. He died in a skirmish near Wrightsborough in Wilkes County in about 1783.
