James Lemmon, son of Robert Lemmon, was born near Hagerstown, Maryland. He served as a messenger boy during the American Revolution when a lad of only twelve years, it being safer for boys to carry messages than men. He carried messages from the camp of George Washington to that of Captain Robert Lemmon (his father) and others. He lived in Washington's camp in Valley Forge and affectionately called him "Uncle George." Towards the end of the war, James entered the Continental Army as a private and served until the end of the War.
In 1800 James Lemmon married Sarah Carr and lived in Bowling Green, Ky. until her death in 1815. He moved his family to Indiana where later he married Amy Rawlins. About 1834 they were lured by free land into Illinois where they settled in Green County -- living neighbors to Roderick Rawlins. In 1844 Roderick Rawlins moved his entire family from Illinois to Texas, and settled in Peter's Colony on a land-grant located partly on Ten Mile Creek in what is known as the southern part of Dallas County. Needing some help in getting his large family to Texas, Roderick Rawlins brought along young Robert Allen Lemmon (son of James Lemmon) and also Carlos Wise, neighbors, and also friends of his own son "Alex." These two boys were so delighted with Texas that they selected 640 acre tracts of land lying next to the Rawlins grant and walked back to Illinois to bring their parents.
Robert Allen Lemmon returned with his father, James Lemmon, his mother, Amy Rawlins Lemmon and his younger brother Jackson Lemmon in August, 1845.
JAMES LEMMON, a citizen of the Republic of Texas, died on July 4, 1858, at his home three miles below Lancaster on the Dallas-Ellis County line. He was buried 90 years ago in Edgewood Cemetery, Lancaster, Texas, near the spot where the Rawlins caravan camped the night it arrived in Peter's Colony in 1844.
James Lemmon is one of the few soldiers of the American Revolution buried in Texas, and the only one buried in Dallas County.
