Henry was born on August 14, 1784, in
Philadelphia, where in 1792, his father and several siblings died from the
yellow fever that was fatally epidemic there during that year. In 1800, when he was the only support of his aged mother and two sisters, he moved to
Lexington, Kentucky, where he resided for ten years, in the employ of Thomas Hart, Jun., brother-in-law of
Henry Clay, and after whose father
Thomas H. Benton was named. In the interest of Hart, young von Phul made numerous trips to the
South, having in charge
keel-boats loaded with flour, lead, bagging and rope. Stopping at the principal towns on the
Mississippi River, he would dispose of his merchandise, taking In exchange cotton, which he would take to
New Orleans and sell, as well as the keel-boats. He would then return on horseback to Lexington, where he would make up another shipment of whatever wares his customers wanted. == Move to St. Louis ==
