In 1828, he changed his name legally to Russell Sturgis.[7] That same year, after his second marriage, he made his first voyage abroad then practiced law in Boston for a time. He sailed for Canton in 1833 on behalf of opium trader John Perkins Cushing,[6] settling for some time in Macau where Lady Elizabeth Napier, wife of British emissary William John, 9th Lord Napier, found him "very intelligent".[8] While he was there, his portrait and those of three of his four children by his second wife, Mary Greene Hubbard, were painted by the English portraitist George Chinnery. In Asia, he entered a succession of trading firms (Russell & Sturgis of Manila; Russell, Sturgis & Co. of Canton; Russell & Co.), and in 1842 he became a full partner.[9]
In 1844, Sturgis retired to Boston to rejoin his children who had been sent there to school after their mother's 1837 death in Manila. He married for a third time, to Julia Overing Boit, and decided to return to China with his family in 1851. The steamer on which they crossed the Atlantic arrived too late to catch the onward ship from London. In their interval there, Sturgis was asked by the senior member of Barings Bank to become a partner.[9] He accepted and ultimately became head of the firm, succeeding fellow American Joshua Bates (husband to Sturgis' cousin Lucretia).[6][a]
Sturgis married three times. He married his first wife, Lucy Lyman Paine (1805–1828), on April 3, 1828.[6] Lucy was a daughter of Henry Paine and his wife Olive Lyman. Her paternal grandfather was Robert Treat Paine, a lawyer, politician, signer of the Declaration of Independence, and the first Attorney General of Massachusetts.[13] Lucy died, aged 22, on August 20, 1828, just four months after their marriage.[6]
On September 28, 1829, Sturgis married his second wife, Mary Greene Hubbard (1806–1837), a daughter of John Hubbard and his wife Jane Parkinson. She bore four children, the youngest of whom (Mary Greene Sturgis) died in infancy:.[5] The other three, all of whom were members of the Codman family, were:
Russell Sturgis Jr. (1831–1899),[14] who married Susan Codman Welles (1832–1862), a daughter of Benjamin Welles [15] and his wife Susan Codman. After his wife's death, this Sturgis married Margaret Cenos McCulloh (1835–1927), a daughter of Maryland SpeakerJames W. McCulloh,[16] who was the center of the landmark Supreme Court case McCulloch v. Maryland, 17 U.S. 316 (1819), and his wife, Abigail Sears.
John Hubbard Sturgis (1834–1888),[18] an architect who married Frances Anne Codman (a half-sister to Lucy's husband Charles).[17]
After the death of his wife Mary, Sturgis married, for a third time, to Julia Overing Boit (1823–1888) on June 4, 1846.[19] She was the daughter of John Boit Jr.,[20] one of the first Americans involved in the maritime fur trade.[21] and his wife Eleanor Auchmuty Jones.
With Julia, Sturgis had four more children:
Julian Russell Sturgis (1848–1904), a novelist, poet, librettist and lyricist who married Mary Maud de la Poer Beresford, a daughter of Colonel Marcus de La Poer Beresford, in 1883.[24]
Through his eldest son, Russell, Sturgis was a grandfather of architect Richard Clipston Sturgis (1860–1951) who was successor to his uncle's practice. He married Esther Mary Ogden and was the father of Richard Clipston Sturgis Jr., also an architect.[29]
