I don't know anything about the relationship of the southern Pledgers to John Pledger (b. 1645-1650, died 1702-1703?), a ships carpenter from Portsmouth, England, who arrived in the Nieuw Nederland section of "West New Jersey" before 1674 on a Dutch ship with his "cousin" (brother-in-law) Hipolyte LeFerve, a French Huguenot, to arrange for the purchase of "Varkens Bloed" (pigs blood), which had been a Dutch whaling colony on the Lenape Lenape's "Makerisk-kitton" (great-tidewater-river).The Dutch claimed that river (the Delaware R.) as "Hudson's south river."
John Pledger and his consort (wife), Elizabeth Leferve, were my great-, great-, great-, great-, great-, great-, great-grandparents.Their granddaughter, Elizabeth Pledger, daughter of John Pledger Esq. and his first wife Dorthy Roberts, married the grandson of John (-the-Finn) Redstreake in 1726.I'm descended from their only son who lived past childhood.
John-the-Finn, born in Varkaus, Finland, about 1620, was a cooper (cask- and barrel-maker) and fur trader in "New Sweden" (circa 1637), "Nieuw Nederland" (circa 1656), then New Jersey -- after the English took control of the region.His consort was Sarah Bright Star, a Leni Lenape woman also called Walela (hummingbird).
Your reference to the Cherokees is interesting because Walela also means humingbird in their language.
You may find some of the information in my other internet postings interesting.And, I assure you, I would be most interested in establishing the relationship of the southern Pledgers to John Pledger from Portsmouth and his wife Elizabeth Leferve (LeFerve) Pledger.
