Jeff Russell (dw@massed.net) kindly supplied this additional information regarding these gravesites:
(Obituary from an unknown newspaper)--
RUSSELL--Abijah Russell died at his late residence in the town of Colton Nov. 30, 1897. He was born in Foster, R.I. March 7, 1805, came into St. Lawrence Co., in 1821, lived first in the town of Parishville thence he came to the town of Colton in 1847. Five years later he built the house in which he has since lived and where he died. He married twice, first to Miss Louisa Briggs, of whom was born 2 sons and 2 daughters. The sons, Alfred and William, survive their father, but the daughters both died before him. The 2nd wife was Mrs. Arbuckle, who died in 1874. Since then the father and two sons, neither of whom ever married, have kept house without the help or society of womankind. To the sorrows of old age first partial then total blindness was added. The older residents of the town remember going to the old man for information regarding the medicinal properties of the various herbs in the neighborhood. As a cooper he was once well and widely known as the maker of the best wooden sap-buckets and butter tubs in the country. In his younger days he was a great hunter and fisherman. From early life he was a religious man and in the course of his life had belonged to both the Wesleyan and Methodist Episcopal Church. The M.E. pastor preached the funeral service at the house and then committed the body to the bosom of mother earth on the old home place.
Jeff goes on to tell that it is his understanding that either the graves and tombstones, or maybe just the tombstones were moved to the present site, before the area was flooded by the building of a dam in that area.
Jeff has done a considerable amount of research on the Abraham Russell descendants (1748-1830), and has recently left a copy of his research at St. Lawrence County Historical Association in Canton.
