Jean Jacques was one of the very last dozen or so Huguenot refugees to London, part of a handful of families from the Cambresis area of France, around the protestant village of Quievy. He arrived less than a decade before toleration and some civil status was regranted to Protestants in France by Louis XVI. The wider Huguenot community itself in London was well in the process of dying out to assimilation. By the time Susanne was baptisng her children there in the 1820's there was barely 4 or 5 children baptised a year (compared to serveral hundreds at the very height of the church's life in 1680's and 1690's), and probably no more than a couple of dozen families regularly using the church (including my own, my g-grandfather was the organ blower, so our ancestors no doubt rubbed shoulders!)
Jean Jacques/John James applied to the French Hospital London March 7, 1825 aged 73, describing himself as a religious refugee from Cambrai, and was admitted a year later June 3, 1826. He died there Aug.23, 1832 aged 79.
His edest son Jacques/James, Susannes brother, applied to be an inmate the same week their father died there on Aug.28, 1832 aged 52 adress No.5 Wellington Row, Virginia Row, Bethnal Green, occupation Silk Weaver. He was admitted two and half years later on March 7, 1835 and died there Oct.27, 1861 also aged 79, being buried by his family at Victoria Park Cemetery, where the New French Hospital was then in the process of being built.
