Here is an authentic probate court of Promfret, Windham, CT document signed in 1865 by Daniel Hunt, Judge of the Probate Court. It begins with a copy of a 1798 document concerning the probate and distribution of Isaac Allyn. It lists various properties that were transferred over the years. At the end are names of people signing the original 1798 documents and a certification to the court that this information is a true copy of the original. There are several hand written pages. This has an original 5 cent revenue stamp. This document gives a great deal of information about the earlier Allyn family and should be of great genealogy interest.
1865 probate court description of of many tracts of land conveyed by Isaac Allen, deceased, to various family members in a 1798 probate of his estate. This must have been a wealthy family because of the 21 tracts of land that was conveyed in 1798. He mentions sons John, Jaber, Joseph, Isaac and Jonathan. He also gave land to Mary Holland, Lydia Gandvens ?, Hannah Cogswell and Thankful Stephens (perhaps married daughters). Also mentions Isaac's widow Lydia Deane (apparently had remarried).
Other names such as points of description of land and officers of the court: Elearen Miles, John Ponist, John Parish, Joseph Gilbert, Moses Clevland, Asa Bacon, Ebineeser Chaffer, Thoma Gvosvenon, Judge, Lemuel Gvosvenor, Clerk, Daniel Hunt, Judge.
I have other Allyn, Allen documents listed on Ebay that go back to 1714 concerning Windam Co. CT. A great genealogy collection on this family.
The Allyn family were original settlers in Connecticutt and Massachusetts in the late 1600's.
The claimants of lands within the bounds of original Killingly having located, described and recorded their lands, the remaining lands within the limits, were given to the proprietors in common, and on October 13th, 1709, the payment of forty pounds through the agency of Captain Chandler having been made, a patent for the remaining lands was given by the governor and company of Connecticut to the following proprietors: Colonel Robert Treat, Major James Fitch, Captain John Chandler, Joseph Otis, James Danielson, Ephraim Warren, Peter Aspinwall, Joseph Cady, Richard Evans, Sr. and Jr., John Winter, Stephen Clap, John and William Crawford, George Blanchard, Thomas Whitmore, John Lorton, Jonathan Russel, Daniel Cady, William Price, William Moffat, James and Joseph Leavens, John, Nathaniel and Nicholas Mighill, John Bartlett, Samuel Winter, Ebenezer Kee, Isaac and Jonathan Cutler, Peter Leavens, Sampson Howe, John Sabin, John Preston, Philip Eastman, David Church, Thomas Priest, Nicholas Cady, John, Thomas, Matthew, Jabez and Isaac Allen. Nearly one-third of these forty-four patentees were non-residents, so that Killingly probably numbered at that date about thirty families. Only a small part of the territory was inhabited, and that mostly in the Quinebaug valley and the open country north of Killingly hill. https://connecticutgenealogy.com/windham/proprietors_of_killingly.htm
