Joseph Keith (who was at one time known as Lieutenant Joseph Keith) was born on 14 Feb 1674/5 (OS/NS) at Bridgewater (now West Bridgewater), Plymouth COUNTY, MA. He was the son of the Reverend James Keith and his first wife, Susannah Edson, daughter of Deacon Samuel and Susannah (Orcutt) Edson. He married Elizabeth FOBES, daughter of Deacon Edward and Elizabeth (Howard) Fobes. Also two sisters of Elizabeth Fobes married two brothers of Joseph Keith (Bethiah Fobes to Samuel Keith,and Hannah Fobes to Timothy Keith.)Joseph married Elizabeth about 1693, probably in Bridgewater. Joseph died on 27 Sep 1730, "in the 55th year of his age," at Bridgewater, and is buried not far from his father and mother in the Old South Street Cemetery, West Bridgewater, MA. Transcription of his tombstone: "Here the memory of Mr. Joseph Keith, who was born Februy (sic) ye 14th day, 1675, and died Sept. ye 27th day, 1730, in ye 55 year of his age. memento mori" And Elizabeth died on 12 Feb 1758, at Bridgewater, MA. She is buried next to Joseph: "Here lies buried Mrs. Elizabeth Keith, Relict [arch. "Widow".] to Lt. Joseph Keith, who departed this life Feb. 12, 1758, in the 81st year of her age." I would be happy to e-mail you a photograph of these two tombstones if you like. All the information above has been put together chiefly from two sources: "The History of Bridgewater, Plymouth County, Massachusetts," by Nahum Mitchell, and "Epitaphs in Old Bridgewater," by Williams Latham. Both books are availabe through the Family History Library of the LDS Church, or from Heritage Books of Bowie, MD.
Another tidbit comes from "A Dictionary of the First Settlers of New England," Volume 3, by Savage:"...made his will 1730, and his widow made hers 1759." Check the Plymouth County Probate Microfilms for those years and you should find those wills listed.
Also, Joseph is made mention of in the will of his father, The Rev. James Keith. He is made a joint executor of the will (30 July 1718) with my ancestor, the oldest son, James Keith II. Also he is inherited of the produce of the house and lands his father owned (which were given to the minister by the town in 1662) and also a share of the minister's clothes. For the will of the Rev. James Keith, see the Plymouth County, MA Probates microfilm, Volume 4, page 184.
You would also do well to get a copy of the Keith book by Larry Keith of Texas (see other messages by him for his e-mail address.) This book gives the entire genealogy of all the children of the Rev. Keith, down to the present day (in many cases). I'd like to hear from you if I have helped in some way. Good Luck! - Joel B. Keith, 7th Great-Grandson of the Rev. James Keith.
