It took me a while to track down the ancestors of Charles Gerrish, the earliest ancestor you listed, but I found them on the Ancestry.com Ancestry World Tree posting by Edward Gerrish Mair, also known as MarshHawk@aol.com.I have asked him to respond to this posting himself to share data, but I can direct you to Ancestry World Tree Project WILLIAM GERRISH FAMILY Newbury MA 1649, where you can click the Index to see Charles Gerrish b. 21 APR 1717.His parents were Nathaniel Gerrish b. 19 OCT 1679 inPortsmouth, NH and Bridget Vaughn b. 2 JUL 1678 in Portsmouth.Nathaniel's father is my ancestor John Gerrish b. 12 FEB 1645/1646 in Newbury MA and his mother was Elizabeth Waldron b. 18 OCT 1645 in Dover NH.John's father was the immigrant William Gerrish b. 20 AUG 1617 in Bristol, Somersetshire, England and his mother was Joanna (Lowell) Oliver b. 1619 in Bristol to Percival Lowell. Joanna's first husband was John Oliver, who died in 1642.That is the William Gerrish whom I referred to in my posting.Your own posting contains many names of recent generations not well known in the Gerrish records and I am sure they are of interest to Mr. Mair and other researchers.Thank you for sharing your data.My own descent is from John and Elizabeth (Waldron) Gerrish's son Timothy b. 21 APR 1684 in Dover, NH.My ancestor Benjamin Franklin Webster is in Mr. Mair's posted GEDCOM.Good luck in further research.
