Cox family.

The story of the Coxe family in America began over three hundred years ago, when in 1684, Dr. Daniel Coxe of London began speculating in land on the American continent, eventually acquiring over one million acres. Little, if any of this land remained in the possession of the Coxe family following the American Revolution, as the new government confiscated proprietary lands. The Coxe land legacy continued after the war, however, through the auspices of the author and statesman, Tench Coxe, who purchased large tracts of land across eight states, focusing primarily on what he believed to be coalfields in northeastern Pennsylvania. Although Tench himself spent the latter part of his life in financial ruin, his prescience secured land and wealth for his heirs and all of their business enterprises well into the twentieth century.
