According to Jacobson pedigree recorded for my ancestor Philip JACOBSON in the heraldic "Visitation of London" (1623), his parents were Jacob JACOBSON of Antwerp and his wife Anne daughter of Philipp DE CROYER of Antwerp. Philip JACOBSON must have been born no later than about 1583 as his married Jane van SOLDT daughter of John van SOLDT of London at the Dutch Church, Austin Friars, in 1603.
I would be interested in learning more about Philip's Antwerp ancestry. As they were apparently armigerous, I gather that they were either burghers with a coat of arms or members of the minor nobility of the duchy of Brabant who probably also engaged in commerce. They were Protestants and Philip fled to England due to the taking of Antwerp by the Roman Catholic forces under the Duke of Alba. In London, he was a jeweller, serving both King James I and his son King Charles I. Philip appears to have been alive in 1643, as he married a second time in that year or thereabouts. He was naturalised a subject of the English Crown having been born in Antwerp himself.
