Krzyzstof was born in Poland, on 19 March 1916 to Stanisława Grynkiewicz-Moszulska and Franciszek Łukasik.​Prior to the outbreak of WW2, Krzysztof was living in Wilno (modern day Vilnius in Lithuania but part of Poland prior to the war).  He studied to become an engineer here and Wilno was listed as his last address (Bazyljanska 3, which still exists but is now known as  Baziljonų gatve. 12. near the Gate Of Dawn) in Poland before his journey began.

 

He was arrested by the NKVD in May 1940, sentenced in December 1940 and placed in Vyatlag camp.  His crime was anti-Soviet agitation.​  In September 1941, he was released indicating that when the Amnesty was issued by the Soviet government in August 1941, he, along with all other Soviet "prisoners" and deportees (including Lucyna and her family) made his way (caught trains/hitchhiked) to the south of Russia to join the Polish Army recruiting camp in Kyrgyzstan.​

 

By family accounts he and Lucyna met and married in Czok Pak camp, Kyrgyzstan.  From the beginning of 1942 until June of the same year he was a shooter (rifleman) with the Railways Branch of the Polish Army in Guzar, Kyrgyzstan.

 

​Records obtained from the Ministry of Defence in Britain show that Krzysztof was ground crew for the 317 Squadron from 1943.​In 1947, he emmigrated to Belgium, where he lived in the town of Ledeberg until his death.

 

Records received from the Civil Affairs Department in Ghent show he died on 19 December 1975 at the age of 59 in Ghent University Hospital.​Krzysztof became a furniture maker after the war, married twice and looks to have had one child, a daughter.​
