Daniel Ninham may have learned to speak English through the family of Catherina Brett who lived in what is now the City of Beacon, New York.
On August 31, 1778, the Nimhams and fifty of their fellow Wappinger were surrounded then killed by Loyalist, British Dragoons and Hessian Soldiers under the command of Lt. Colonel Simcoe in the Battle of Kingsbridge Cortlandt Ridge in what is now Van Cortlandt Park in the Bronx.
