Johann Heinrich Thonemann was – as pointed out above – the third child of Johann Heinrich Thonemann and Gertrud (née Hoppen).
He was born in Scherfede on 1.11.1719; died on 28.8.1762 – not yet 43 years of age. The marriage with Anna Maria Wiemers took place on 28.2.1750; three children were born during the twelve-year marriage: 1. Anna Maria Christina, born in Scherfede on 18.4.1751; 2. Johannes Heinrich, born on 8.4.1753, died in Scherfede on 25.3.1814; 3. Joes Christoph, born in Scherfede on 4.2.1756. Anna Wiemers was born in Scherfede in 1716 and died at the age of 84 on 13.1.1800. Johannes Heinrich, the second child, continued the Scherfede branch.
Joes Christoph Thonemann, the third child of Johann Heinrich and Anna Maria, née Wiemers, was born in Scherfede on 4.2.1756.
On 9.7.1784 at the age of 28 Christoph married Eva Maria Kohaupt – 23 years of age – born in Scherfede in 1761. It cannot be seen from the official records if Eva Maria came from Scherfede or Rimbeck. In any case between 1784 and 1790 Christoph moved to Rimbeck, as his son Johann Heinrich was born in Rimbeck 1790.
Joes Christoph died at the age of 82 on 25.1.1838. His wife died after a marriage of nine years at the age of 32 on 18.3.1793. In 1793 Christoph married again. His second wife was Eva Margareta Günther, born in 1761. On 28.10.1837 she died at the age of 76.
The following five children resulted from the first marriage: 1. Matthias, born on 14.8.1785; 2. Johann Heinrich, born on 7.1.1787, died 1787; 3. Johann Bernhard Heinrich, born on 9.6.1788; 4. Johann Heinrich, born on 14.2.1790; 5. Anna Maria Elisabeth, born on 17.2.1793, died in the same year.
Two children resulted from the second marriage: Franziskus Antonius, born on 24.1.1794, died 1794 and Johann Franziskus Josef Antonius, born on 20.6.1801.
The fourth child from the first marriage is the founding father of the Thonemann family, who continued the family in Rimbeck: Johann Heinrich Thonemann, born on 14.2.1790 in Rimbeck.
