There are many anomalies in this record.  Who was the informant, the servant?  Listed four households from Timothy NOLAN-HOPKINS. 

6.  Arthur Wilmot Ackerman.  1928.  "Memoirs of Deceased Members of the New England Historic Genealogical Society."  New England Historical and Genealogical Register 82(Jan): 99-121. 

WARNING:  there is something very wrong with this memoir with regard to Edward's wives.  The author has Edward married first to Georgina SMITH, in 1876; then second, to Helen THOMPSON, after Georgina's death in 1920.  However, the 1900 Census shows our subject with wife, Helen, married 22 years!  We have to take the census as the primary record, which means this memoir — despite the (irrelevant) credentials of its author and the esteem of its publisher — is not to be trusted.  (But how could he get it soooo wrong?)
p. 104	EDWARD WHITING HOPKINS, of San Francisco, Calif., a Pilgrim Tercentenary member since 1919, was born at China, Mich., 26 April 1848, the seventh and youngest child of Samuel Frederick and Mary Ann (Keeney) Hopkins, and died at San Francisco 18 January 1926. He was a descendant of John1 Hopkins, who was in Cambridge, Mass., in 1634 and at Hartford, Conn., in 1636, through Stephen,2 1634-1689, of Hartford, John,3 1665-1732, Capt. Timothy,4 1691-1748, of Waterbury, conn., Rev. Samuel,5 1721-1802, B.A. (Yale, 1741), M.A. (ib., 1744), D.D. (Brown, 1790), a distinguished Congregational minister and theologian, who held pastorates at Great Barrington, Mass., and Newport, R.I., Moses,6 1751-1835, whose wife was Ann Whiting, Mark,7 and Samuel Frederick,8 his father, who was born at Hinsdale, Mass., 15 September 1803, married Mary Ann Keeney of Hartford (born at Hartford 21 July 1807, died in 1891, daughter of Asahel and Theodosia (Woodruff) Keeney), and died in 1884.  He also traced his ancestry to Governor William Bradford of the Plymouth Colony. Mr. Hopkins went to California in 1870, and resided at Sacramento while serving as assistant treasurer of the Central Pacific Railroad, of which his uncle, Mark Hopkins, had been one of the organizers and was at that time treasurer.  In 1878, upon the death of his uncle, he became treasurer, and removed to San Francisco.  In 1882 he severed his connection with the railroad and organized the Union Ice Company, of which he was president until his death.  In financial circles he was active in establishing a number of banks, among them the Mission Savings Bank of which he ws for a time vice president, the Mission Bank, and the Mercantile Trust Company, in which he was a director.  At the time of his death he was a director of the Bank of California. His benefactions were many; but he shunned publicity, and few knew of his gifts.  Among them may be mentioned a fund of $25,000 for the Leland Stanford Junior University, to be used to help deserving but needy students in completing their college course. He was a member of several clubs, among which were the Pacific Union and the Bohemain, Olympic, Menlo Country, and San Jose Country Clubs.  His summer home was at Menlo Park, Calif.  Mr. Hopkins married first, at San Francisco, 25 October 1876, Georgina C. Smith, who died 7 March 1920, daughter of Henry Stephen and Mary Henrietta (Higginson) Smith, of a family of Philadelphia Quakers; and secondly Mrs. Helen M. (Thompson) Tourillotte of New York.  His sec-
p. 105	ond wife survives him, together with four of his five children by his first wife, namely, Mrs. Augustus Taylor (Helen Hopkins) of Menlo Park, Mrs. Stewart S. Lowery (Edna Hopkins Taylor) of Menlo Park, Samuel Hopkins of San Francisco, and Mrs. John Cheever Cowdin (Florence Hopkins) of San Francisco.  His third child, Georgina Hopkins, was the wife of Frederick William McNear and died 21 February 1920.
