For anyone interested in this line: The will of Andrew Pegan was filed in Lancaster Co., PA, Will Book F, Vol. 1, p. 86. Witnessed by Hugh Penny and John C. Maffet on 9 Sept 1788. Will proved 13 Jan 1789.
In this will "Andrew Pegan Sr. of Martick Township... Yeoman" gives to his "well-loved son John Pegan" interest in stock; to his "well-loved son James Pegan" land and 1/2 interest in horses & stock; to his "well-loved son Andrew" the other half of cows, sheep, etc... He mentions his daughter Jean Lusk and his daughter Mary Downing -- to each of whom he left 7 shillings, 6 pence. To his daughter Margaret Herron and his granddaughter Ann Herron he leaves "puter" dishes. To an unnamed granddaughter, daughter of son James, he leaves feather bed and bedclothing.
He named John Caldwell ("trusty friend") and "James Pegan my son" as executors.
Note that the spelling of the surname varies in this and other documents of the time: Pegan, Pagan or Peagon. For example, the Index to 1751 Lancaster Co., PA tax records lists Andrew Peagon in Martic Township; the same person (apparently) is listed as Pagon in 1754.
