Jan Rijnders was a tax consultant and member of the Resistance. 
He was from Valkenswaard and is also buried there. During the war he worked with the White Brigade or Secret Army in Belgium. [1#3]
During the German occupation, he went into hiding to avoid being sent to do forced labor in Germany, and came into contact with the organized resistance. 
In the archives of the Oorlogsgravenstichting (War Graves Foundation) is a statement from the municipal police of Valkenswaard from the postwar period:
During the occupation he worked in the resistance. In doing so, he collaborated with members of the so-called White Brigade in Belgium.
He and his entire family were absolutely reliable politically. His father and his two sisters spent some time in the German concentration camp VUGHT. One of his brothers deserted as a policeman when he had to carry out orders for the Germans. He tried to escape to England, but was probably killed on the way. [1#3]
The website brabantsegesneuvelden.nl says the following about Jan:
After the liberation of the south of the Netherlands in September and October 1944, he volunteers for military service and is allowed to train with a US Army unit. He participates in the Allied encirclement of the city of Aachen and is mortally wounded by shrapnel from a fragmentation bomb. He succumbed to his wounds there on October 18, 1944. 
We have included Jan Rijnders in this list because he died just over the border as a member of the U.S. forces that liberated South Limburg just before. We do not know if he was already a member in Limburg.
He is buried in the Catholic cemetery in Valkenswaard. [1#10]
He is listed in the “Erelijst 1940-1945” (Honor Roll of the Dutch Parliament).
