I doubt that we have an intersection of ancestors her. My Peacocks definitely came from the New Jersey area in the 1800s (rather than Virginia, as yours did). There could be a conection in the earlier years (before 1830) because I don't have any information on the predecessors to Samuel peacock, who was born around 1835. Below is the the information I have on all of my Peacocks who had an association with Washington D.C.
1 Samuel Peacock

The birth date is an estimate based upon the birthdate of his oldest child.
Samuel and Elizabeth lived at Finley Station, Upper Deerfield Township(?), Cumberland County, New Jersey in 1888. They had a large family, birth order unknown.
Finley Station was located roughly 3 miles northeast of Bridgeton, NJ, and had a population of 57 people in 1895.
Prior to living in Finley Station, they seem to have lived in Downe Township, Cumberland County, which includes the town of Fortescue, where their oldes son William was born. Samuel Peacock, from Downe Township, Cumberland County, New Jersey, was mustered into the 25th New jersey Infantry, Company D, of the Union Army as a 1st Lieutenant on 5 Sep 1862.
