Thanks to Photo Volunteer Carolyn Angeline who went carefully through the soil and encountered a layer of white powder that must have been the former stone. Carolyn uncovered several other areas and found the same thing.
Carolyn went as far as she thought in good taste could dictate. Carolyn believes this stone is lost to time.

Jacob3 Skolfield (Thomas2, Thomas1) was born 7 November 1779 in Brunswick, Maine. In some records his birth date was listed as 23 May 1780; married, first, Hannah Chase Stanwood, daughter of William Stanwood and Hannah Chase, on 5 May 1807 in Brunswick, Maine; married, second, as noted in the Bowdoin published records but without a date, Rachel Ann Wilson, daughter of Actor Wilson and
Apphia/Effira Pennell. There were no children of Jacob's second marriage. Jacob lived on Mere Point in the house afterward owned by his grandson Thomas B. Skolfield.
He died 30 May 1860 in Brunswick, Maine, and was buried in Maquoit Cemetery, Brunswick. There is a War of 1812 marker on his grave.
Hannah Chase Stanwood was born 6 December 1788 in Brunswick, Maine; died 31 December 1844 in Brunswick, and was buried in Maquoit Cemetery, Brunswick.

Brunswick, Maine. He died 12 February 1893 in Topsham, Maine. His maritime career
was recorded by Erminie S. Reynolds and Kenneth R. Martin in The Skolfields And Their Ships, as follows: "William received his protection certificate in November 1835. He made two voyages in the ship John Dunlap, Clement Skolfield (1808-1878), master, in 1837- 1838. In 1841, William was mate in the ship Brunswick (582 75/95 tons), William Stanwood, master, built in the Stanwood yard by Stephen Harris and not to be confused with the vessel of the same name built by William's father, Jacob (1779-1860). In 1842, he was master of the brig Mary Pennell. From November 1844 to April 1850, he was part owner and master of the bark Sarah Ann, named for his wife who accompanied him on all his voyages. He owned 1/4 of the new ship General Dunlap, was her first master in 1850,
and remained with her until December 1854, when he turned command over to Joseph S. Badger. William and Sarah Skolfield settled in Topsham. William represented that town in the state legislature in 1862 and 1874, and was active in banking circles, holding the presidency of the Pejepscot National Bank from 1866 to 1875." A letter from T.B. Skolfield, written 2 April 1893, is quoted by Esther Skolfield Schmidt in her notes: "Uncle William died of heart failure. He had taken his bath on this Sunday he died. Aunt Sarah heard a slight noise, looking towards him she noticed a change in his face, going to him she found him dead. He was sitting up in a chair at the time. Uncle William's funeral was largely attended. I may say he looked the handsomest of any dead person I ever saw. The
bearers were Captains William Otis, Francis Otis, John Bishop, and young Capt. George Skolfield, (1860-1921) Link's boy." His obituary read: "His home on the shore of Casco Bay, Maine, brought to him the influence of the sea in early life .retiring from the sea, he was an active citizen in Topsham, Maine, for many years and was for many years president of the Pejepscot National Bank of Brunswick. From 1862 to 1874 he represented his town in the Maine legislature. A friend of education, he helped in the endowment of scholarships at Colby College. He was modest and retiring, a deacon of the Topsham Baptist Church. A picture of Captain Skolfield has been presented to the Curtis Memorial Library, Brunswick, by the sisters Martin." He was a member of the Pilgrim Society, founded in 1820. A painting of the Sara Anne, from his home, was given by Erminie Skofield Reynolds to the Maine Maritime Museum. His home was built by his father Jacob.
