My great x4 grandfather was at St. John’s Church when Patrick Henry gave his speech, he and 4 of his brothers signed up as Minute Men right afterwards, he served in the war and guarded prisoners for Layfayette.
He was born in 1748 in Hanover County, VA near Patrick Henry and died in 1850 in Macon County, TN at the age of 102 where he had claimed his 2,000 acre war acreage and our relatives still live there.
His grandfather died at 99, his father at 88, his son at 96.
My father died in 2011 at 93.
