Wolfgang Marcus Gualtherus

In April 1608, in Vollenhove, Gualtherus married Aeltjen (Aelke, Aleijda) Wolfsen (baptized 8 August 1583 in Zwolle), who was alive in 1639.

[4] As a Remonstrant, Gualtherus conducted a written debate about predestination with his fellow student Johannes Urbanus, among others.

After the counter-remonstrants had prevailed at the Dordrecht synod, Gualtherus had to give up his church offices in August 1619.

The reason for this was an overthrow of the Kampens government due to probably correct accusations, secret contacts to the banned Remonstrant leaders Johannes Wtenbogaert, Conrad Vorstius and Simon Episcopius to have entertained.

The Kamper magistrate continued to put pressure on him, but could not prevent him from living there in seclusion for a long time.

At the funeral of Conrad Vorstius, who, like him, had emigrated to the Duchy of Schleswig-Holstein-Gottorf after the Dordrecht Synod, he delivered the eulogy.

Gualtherus was appointed rector of the probably not large Latin school in Friedrichstadt and received his first salary on July 29, 1624.

In October 1631, Gualtherus presented a first version in High German, which the ducal chancellery was to revise and confirm.

The city charter drafted by Gualtherus became effective on March 22, 1633 and appeared in print in 1635 in a Dutch version.
