I just visited Winthrop, ME to try and find Benjamin Allen who I beleive is the brother of Philip Allen of Attleboro, MA (sons of Benjamin and Mary (Torrey) Allen.
Benjamin Allen was the first postmaster in Winthrop and owned a Mill which he later sold to Liberty Stanley the son of Solomon.
Solomon owned land adjacent to Philip Allen.
There is a cemetery (I could not locate the name) on Main Street across the street from the Congregational Church.Here I found the gravesites of Solomon Stanley and his wife and Peter Stanley and his wife.In front of their stones was the stone of Philip Allen but Benjamin could not be found.This group of stones was the first stones on the right as you enter the cemetery.
I also searched several cemeteries in Turner, ME where Benjamin likely went to start a new Mill but again found nothing.
Here is what I have to date if anyone out there thinks they can help.
History of Winthrop, Maine, by Everett S. Stackpole, published by "Press of Merrill & Webber Co., Auburn, Maine", 1929. Are the following entries: Page 196 & 197: "THE FULLING MILL PRIVILEGE The second dam on the stream for power purposes was built by Cyrus Baldwin on the site of the present cotton mill dam of the Winthrop Mills Company. Mr. Baldwin came to Winthrop in 1790 and in the course of that and the next year built a mill and put in machinery for the fulling and dressing of cloth. The cloth was made from wool grown by farmers in of the vicinity, carded and made into rolls at the mill, (work previously done by hand at home) spun and woven by their wives and daughters and carried to the mill to be fulled, colored and dressed. When finished it was taken home and made into clothing for both sex. Mr. Baldwin's stay was short. In 1792 he sold the new mill, now ready for operation, and removed to Fayette Mills. On the fine water power there he built a like mill which he soon sold and went elsewhere. Benjamin Allen, who, it is believed, came with Mr. Baldwin, was the purchaser, and he carried on the business until 1797 when he sold to Solomon Stanley and moved to Keene's Mills in Turner."
Page 222: "Matthew Blossom of Monmouth and Benjamin Allen of Winthrop were the carriers of the mail, Blossom taking it from Portland to Winthrop and Allen from Winthrop to Wiscasset and return. The time for the round trip depended much upon the conditions of the roads. Post Offices were established in the towns through which the mail was carried. Benjamin Allen was appointed postmaster of Winthrop, his commission being dated 1 Jan. 1795. Allen's dwelling was a small one-story house at the foot of Fish Street, nearly opposite the mill of S. C. Davis, and the office probably was kept in his house."
Page 254: (Genealogies) "Benjamin Allen bought a mill for carding wool, in Winthrop Village, in 1792 and operated it till 1797, when he sold to Liberty Stanley and soon after settled in Turner at a place on Twenty Mile River and built mills there, now known as "Keene's Mills". He was the first postmaster in Winthrop. His dwelling was on the west side of the stream at the foot of Fish Street. Afterward his house was enlarged and was the residence of Luther Whitman in 1852. Later it was destroyed by fire. Here, undoubtedly, was the first Post Office. Mr. Allen married Sarah, daughter of John and Hannah Jennings of Wayne. Her mother was Hannah Newcomb, widow of Jonathan Sturgis. She was born 2 April 1777 at Sandwich, Mass. 5 ch. recorded. Josiah A. b. 6 Aug. 1788; d. 2 June 1794.
