David is believed to be the son of Thomas and Priscilla Walton only because he was old enough for the third generation and is not known to be a member of another family (Byberry Waltons, page 19).
Byberry is a township in the northeast corner of Philadelphia County, Pennsylvania. The Walton brothers were early settlers. Moreland Township was just west of Byberry. When Montgomery County broke off in 1784, Moreland was divided into two townships, both called Moreland. In 1917 the Montgomery County Moreland split into Upper Moreland Township and Lower Moreland Township.
The Manor of Moreland was composed of a tract of ten thousand acres, and was created, in 1682, by a grant from William Penn to Dr. Nicholas More. Most of the Manor was in Philadelphia County, but is now
Moreland Township, Montgomery County, Pennsylvania.
