Gerthrut Köhl married in 1692 the Chur merchant Georg Laurer (1667-†1724), son of Jeremias Laurer and Anna Heim, and a grandson of the respected and wealthy judge Jeremias Lurer, who was a member of the Court of Profects and from 1647-1654 and 1664-1671 a member of the Chur City Court. Bernhard von Köhl must certainly have held his protective hand over this marriage and described the marriage with Georg Laurer as "well given". The couple had eight children, five of whom reached adulthood. Gerthrut died at the age of 48 and did not live to see the birth of her first grandchild. Her children and grandchildren were to go far in Chur, becoming priests, head guildmasters, councilmen, town aldermen, judges and one even mayor.
Children of Gerthrut Köhl and Georg Laurer:
