I have a William Peacock (b. 1859 in NJ; d. 1944 in DC) who was apprentice printer at the U.S. Printing Office and printed the Congressional record at night to be on the desks the next morning.
He served in the Spanish-American War, Lieutenant, 4th USA Infantry; his burial flag is in possession of Oris Friesen (that's me.) He married Kate Stewart Pickels in Wilmington, DE, on 27 Nov 1883.
They had 6 children: isabella, Samuel, Natalie, Catherine, William and Ruth. Ruth was born in 1903 in the DC area. the others were born in NJ.
Could there be a connection here?
