More Info :)

Johnny Appleseed (born John Chapman) was a direct descendent of Edward Chapman, who came from Yorkshire, England, to Boston in the 1640s and became a prosperous farmer and miller in Ipswich. John was of the sixth generation from Edward. He was the second child of Elizabeth Simonds and Nathaniel Chapman, who were married at Leominster, Massachusetts on February 8, 1770. John was born in Leominster on September 26, 1774, and was baptized with his sister Elizabeth in the Congregational Church on June 25, 1775, the day his father and mother were received into that church. John's father, Nathaniel, was a carpenter, a farmer, and a Revolutionary soldier. So far as any records show, he was a man of little means, though there is a tradition that he lost two good farms in the service of our country. A letter from Elizabeth to Nathaniel, dated June 3, 1776, suggests that she was suffering from an advanced case of tuberculosis. At that time, Nathaniel was with a company of carpenters attached to General George Washington's headquarters at New York. In this letter, Elizabeth states that she has money for her needs, though she has not bought a cow, for cows were scarce and dear. This was a time of hardship and war-time inflation when many a colonial mother had a hard time caring for her children. On June 26, 1776, Elizabeth gave birth to her third child, a son. On July 18th, she died, and within two weeks, according to family tradition, the baby, too, was dead. Little John, not yet two years old, and his sister, Elizabeth, were cared for by relatives. After Elizabeth's death, Nathaniel continued to serve in the Continental Army until the summer of 1780 when he was honorably discharged. That same summer he married Lucy Cooley of Longmeadow, Massachusetts. To them were born ten children. We do not know if John and Elizabeth ever went to live with Nathaniel and Lucy, but we do know that John maintained close relationships with the family. Again according to family traditions, John at the age of eighteen persuaded his half-brother Nathaniel, a lad of eleven, to go West with him. This was in 1792.
