Boyd Miller (ca. 1778–1865), merchant, joined a London firm by 1801. Two years later he began a partnership from abroad with William Brown, of Lynchburg. After Brown’s death in 1811, Miller entered a new partnership with Archibald Robertson and Samuel Read, which ended in August 1819. Miller lived in Virginia himself from about 1815 to 1819. Even after his return to London in about 1820, he retained his American investments and sought to settle these accounts into the 1860s. Miller continued as a merchant in London and died in nearby Mitcham (Post-Office Annual Directory For the Year 1801 [London, (1801)], 160; Post Office London Directory For 1820 [London, (1820)], 242; Post Office London Directory For 1865 [London, (1865)], 572; Va.

For the bond of 1820. mar. 5, see TJ to Archibald Robertson, 7 Mar. 1820. In March 1823 TJ calculated that he owed Miller’s agent William Barret “1150,” due “May. 23.” (MB description begins James A. Bear Jr. and Lucia C. Stanton, eds., Jefferson’s Memorandum Books: Accounts, with Legal Records and Miscellany, 1767–1826, 1997, The Papers of Thomas Jefferson, Second Series description ends , 2:1393). For a later estimate of his debt to Miller, see TJ’s List of Debts and Assets, 1 Apr. 1823. TJ’s account with Miller was still unpaid in 1829 (ViW: Boyd Miller and Archibald Robertson Ledger, 1819–57).
