Person
T.B. MacKay
Commission merchant T.B. MacKay served on the 1850 Boston Vigilance Committee.
In his Reminiscences of Fugitive Slave Law Days in Boston, Austin Bearse listed T.B. MacKay as a member of the Boston Vigilance Committee. This organization assisted freedom seekers coming to and through Boston on the Underground Railroad. 1
Other committee records as well as the 1850 Boston City Directory list MacKay at 49 and 51 Pearl Street, working as a commission merchant. He lived nearby on Winter Street. According to the account book of Vigilance Committee treasurer Francis Jackson, MacKay donated money to the organization in 1851. Other than this donation, however, MacKay’s further contributions to the group remain unknown.2
T.B. MacKay may be the merchant Tristram Barnard MacKay, though other records place him in Concord, Massachusetts around the same time. It is possible, however, that he maintained two residences: one in Concord, and one in Boston.
Born in 1802, Tristram Barnard MacKay worked as a merchant and passed away in 1884 in Kittery Point, Maine. His remains are buried in Mount Auburn Cemetery in Cambridge, Massachusetts.3
