On September 1, 1682 a band of about one hundred persons set sail from Deal, England on the "Welcome" with William Penn bound for his recently acquired province in the new land across the ocean, where they could worship in freedom. they reached Newcastle, on the Delaware River October 27, 1682, one-third fewer in number because of the ravages of smallpox on shipboard.

Among those who came to the new land were James and Joan Moon and their six children, Sarah, James, Jonas, Jasper, Mary and Roger. The family settled near Fallsington, in Bucks County, Pennsylvania, on a land grant given them by Penn.

James Moon was actively associated with the affairs of Bucks County, his name frequently appearing on the early records of the courts of that county after 1685, as a member of Grand and Petit Juries, and as serving in various capacities by appointment of the court, up to the time of his decease on September 1713.

Joan Burgess Moon, wife of James, received a legacy from her parents or other relatives in England in 1695 and obtained a certificate from the Bucks County Court on December 11, 1695 to enable her to receive it, the court entry of which is as follows: "A Certificate of Joan, the wife of James Moone, being alive signed in Court she being then there present."

She survived a quarter of century, dying December, 1739 in her ninetieth year, at the home of her son, Roger.
