Hope this reaches you considering your message dates March 2002. Only nearly 9 years late! I have some info on this family although it is not one of my main lines of research. Here is my data:
Christian Penn (b. abt 1606, England; d. 1684 Middleborough, Plymouth Co., MA) - dghtr of George Penn (b. 1571, Birdham, Sussex, England - d. 11.4.1632, Plymouth Colony; and Elizabeth Brinksworth (B. 1571).
Christian, a Mayflower passenger married two Mayflower passengers and had surviving children from both marriages: (1) m. Francis (MP) Eaton, m. abt 1624: Children: (1A) Rachel Eaton, b. 1625 - m. Joseph Ramsdell, 1645, Plymouth, MA: one child, Daniel Eaton Ramsdell (1649-1721) married Hannah Coswell/Caswell leaving many decendants - all carrying descent from at least two Mayflower passengers. (1B) Benjamin Eaton, (1627-1711) - m. Sarah Hoskins, with many descendants (2) m. Francis (MP) Billington, m. abt 1634 and had at least four Penn Billington offspring leaving a long line of descendants - all again carrying descent from at least two Mayflower passengers. Indeed, daughter of Christian Penn & Francis Billington, Martha Billington, m. 1660 Samuel (MP) Eaton, leaving at least two children who in turn left long lines of descent, in this case carrying three lines of descent from Mayflower passengers.
There is also an interesting ancestry involving Christian Penn, her British ancestors and line of important descendants involving the Penn family in American history. She and her family leave famous direct decendants in at least two cases (1) the signer of the Declaration of Independence, John Penn, and (2) US President James Garfield. (Probably others but my information on her is not complete.)
I do have more on her. Let me know if you need further info.
