Hendrik Hoeymakers was a farmer and married to Maria Catharina Jakobs, born on September 7, 1886. [1#2]
His surname is spelled Hoeymakers by relatives and acquaintances, but many officials have changed it to Hoeijmakers.
The home of H. Hoeymakers-Peeters was a transit shelter for refugees and people in hiding from the Horst sub-district of the LO.  This was a daughter-in-law. Apparently the whole family took part.
Although an occasionally operating combat group was formed in Horst in 1944, for the most part of the occupation there was no group that dealt exclusively with sabotage and raids. In addition to helping people in hiding and refugees, the resistance in Horst and Sevenum was involved in activities that actually fell within the competence of the Knokploegen (combat groups). 
From 1943, the LO was the main resistance organization, in which OD people also participated.
Hendrik was arrested in Kronenberg in the church raid on October 8, 1944.
Many men and boys were deported to Germany for forced labor. Among them was father (Hendrik Hubert) Hoeijmakers, two sons and two sons-in-law 
According to the municipality, 700 male inhabitants of the municipality of Sevenum were deported to Germany for forced labor on this day. [1#3]
Of them 75 were inhabitants of the village of Kronenberg. See the monument: From Kronenberg, 75 men were deported. 9 of them did not return. 
His wife wrote on September 8, 1946:
My husband was deported to Germany on October 8, 1944, worked for a time in a factory in Watenstedt, fell ill there and died in a hospital in Reppner on March 11, 1945.
We also do not know how and where he was buried and would therefore like to find out more about this, if this is still possible through your service. [1#15]
Watenstedt and Reppner are both near the industrial town of Salzgitter in Lower Saxony. 
His son Jeu was murdered in the forest on the same day.
Hendrik Hoeymakers and his son Mathieu (Jeu) lie side by side in the
family grave in the Catholic cemetery in Kronenberg. [1#9]
