In the Bible, "John Trenchard the son of John and Elizabeth Trenchard was Born in his Grandmother's house in the township of Huntington in the County of Suffolk on the Island of Nassau in the Province of New York on Friday the 27th Day of October 1752." Then it lists Scorpian and has signs for the day and hour. The Father, John Trenchard, was b 11 December 1707 in London, the Mother, Elizabeth, daughter of John and Pteriah Rulan (this is difficult to read and spelling may be wrong) was b 10 December 1722 and d 19th of February 1759. There is also a Henry b to John and Elizabeth on the 31st day of October 1754 in the house of Daniel Wait-Smith in the town of Hempsted, in Queens County on the Island of Nassau in the Province of New York . Samuel Trenchard b to the father John and 3rd wife Jeminia Doty on 13 April 1762 in the township ofHorseneck,in Green-County of Fairfield - Connecticut. Spaces are parts I can't decipher. I don't know if there is a link to your John Trenchard with any of these male children but if so there is most likely one generation missing. I am waiting for some other papers, if I find more on the male children will let you know.
