Jakob von Gerlach was a Landrat and president of the Berlin Missionary Society. A second tie links the two families: Bertha von Gerlach, daughter of Wilhelm, married Wilhelm von Kröcher.
An ancient noble family of the Altmark. The von Kröcher family is linked to the von Gerlach twice over – once by marrying in (Sophie), once by marrying out (Bertha, see "Von Gerlach in Other Houses"). Further details remain to be added from the Genealogical Handbook of the Nobility.
