Montmollin's maternal grandfather was
Jonathan Edwards the younger, thus he was a
first cousin, once removed, to
Aaron Burr; as vice president, Burr stayed at the Montmollin home in 1802 while visiting Savannah. Montmollin married at Savannah, in 1842, Miss Harriet M. Rossignol. In 1848, he was a city marshal of Savannah, where he owned a plantation. Montmollin was president of the Mechanics' Savings Bank of Savannah, which had been organized in 1854, and had capital amounting to in 1857. Beginning in 1856, he funded the construction of a still-extant three-story brick building now known as the
John Montmollin Warehouse. The third floor was a
slave pen (after the city was occupied by Union troops during the
American Civil War the building was turned into a school for the city's African-American children, most of whom had never before had the opportunity to learn how to read or write). In December 1858 Montmollin sought to purchase "one or two gangs of rice field Negros." According to his daughter-in-law, who was interviewed in 1931, Montmollin sought to
reopen the transatlantic slave trade and was responsible for organizing the illegal human trafficking transport

A handkerchief, which he had in his hand at the time of the accident, was still tight in his grasp." Following Montmollin's death, his widow found that "her husband died owing debts of more than $30,000" and so in 1863 petitioned a court for permission to sell the estate slaves she had inherited. Permission was granted and she sold 81 slaves in Savannah in April 1863 for . ==See also==
