In 1808, Philip Drum (son of George Sr.) bought land in Luzerne County from Benjamin Rush, who was a close advisor to George Washington during the American Revolutionary War and signed the United States Declaration of Independence. In 1810, Philip established Drums' first carding mill on the Little Nescopeck River. In addition, Philip established the first wool-processing mill in 1835; it was located a short distance from the carding mill. In 1814, George's second son, George Jr. (born Oct. 16, 1792), bought land next to his brother Philip. Philip bought additional land in 1814, 1826, 1836, and 1847. George Sr., George Jr., Philip, and other Drum family members owned vast acreage of land in Drums, Conyngham, and surrounding counties. George Drum's two century old estate still stands in immaculate condition in Conyngham and is a fine example of colonial architecture. George Sr. and George Jr. both died in 1831. On February 27, 1858, Philip died at the age of 71 in Drums, Butler Township.
