Henry Boldero & Co. emerged as one of two successor companies to Boldero, Carter & Boldero in 1769.
Appearing in various iterations, the bank was formed c. 1765 when the partnership of Boldero, Carter and Boldero split. One of the two successor firms, Henry Boldero & Co., became Boldero, Kendall & Adey, then Boldero, Lushington, Boldero and variants. It failed in 1812.
