We have much to discuss!!! Too much for here, now! But, I want to respond promptly to provide you a snapshot of where we stand on my end and clarify your earlier confusion.
Yes, my information has been improved upon / refined since my earlier postings. Do not take them as Gospel until we share detail.
1. (H)esther Milham did marry John Parks, not James. John & (H)esther had the 4 children cited.
2. My (and other cousins', whom we shall discuss and e-meet later) Parks research centers on the marriage of James Parks and Mary Hanbury/Henbrey, both of Ewhurst. They had 14 (NOT 15) children - all b. Ewhurst. We refer to these as "The Parks Fourteen". They were:
3. I descend from #10 Henry. I am in contact with living descendants of ANN, JOHN, JOSIAH, and HENRY. We are actively persuing living descendants of all 14. (Although we don't know of any marriages for MARY or PHILLIP.)
4. In the 1820's "some of the parishes in the east of Sussex adopted the practice of sending off annually, a part of their surplus population to America". As a result of this "practice", in 1827, MARY, MARTHA, ANN, JAMES, Jr., JOHN, JOSIAH, JOSEPH, HENRY and PHILLIP, and their respective families emigrated to New York. (Apparently courte$y Ewhurst Parish!)
5. They sent letters back to Sussex imploring the remaining family members (including extended family) to leave the tyranny of England behind and come to the land of plenty. One of these letters, from John & (H)esther, refers to a cousin DAVID in NY. (This may have been Hesther's first cousin DAVID MILHAM you mentioned.)
6. About 1829, all of the remaining 14, plus the parents (James & Mary) came to NY with the exception of #5 SARAH. She married a cousin and remained in Sussex.
7. 28 Aug 1913, a reunion was held on Long Island (NY)with descendants of HENRY, JOHN and STEPHEN. 43 people attended and formed the "Parks Family in America" association. Reunions continued annually until WWI broke out and apparently "got in the way".
8. I want to share our connection with my fellow "cousins-persuing-cousins", a descendant of JOHN in particular, and get into detail with you and them. Meanwhile, please e-mail me directly as we wish to respect the "Living" descendants' privacy.
9. I lived on Long Island all of my life until last year when my wife (Marci) and I moved to North Carolina. (Marci's employer is based here and it was a career move for her.)

PS. Courtesy of a prior career, I spent 3 mo Down Under. Great people!!!!! Unfortunately, most of it was in the outback but still a great experience.
