Originally from Hesse, they are direct male-line descendants of the Reginarids and therefore one of the oldest still existing noble families in Europe. They carried the titles Knight, Lord, Count and Freiherr of different dominium plenum and dominium directum. This noble family thrived in the Middle Ages between 1300-1600 and had branches in Hessen, Saxony, Pommern and Westphalia (County Mark and Fbd. Münster) Falken. The coat of arms this family used in Hessen and Thüringen and Saxony
is different from the branch who was ruling parts of Pommern and Westphalia. The latter used a Griffin which was derived from the coat of arms of the "Greifenhaus" in Pommern. The griffin coat of arms still refers to the coat of arms used in Hessen and Thuringia and Saxony by using the same horns and red and white colours in the horns. This Falcken family, whose patriarch is “Knight” Heyso Falcken, (mentioned in 1359) is a bastard son. of the House of Hesse (they are descendants from the House of Reginar). The territory of the Falke/Falcken/Falken expanded between 1359 and 1557 from the Middle of Germany to the East.

One of the Falkenreck estates (originally 250-300 acres), next to one of the Raesfeld estates in Gütersloh (Sundern), was sold in 2015 to the municipality of Gütersloh.
The Falkenreck estate is called Falkenrecks Heide.
