[2] Following his father's marriage to Alicja Matter on 3 June 1896,[3] Stanisław was born on 4 November 1898 in Jabłonków (now Jablunkov in the Czech Republic) in the Trans-Olza region (at that time occupied by Austria).

[4] At age seventeen Grodyński was conscripted into the Austrian Army in May 1916 [5] he began military training as a rifleman in 100 Reserve Battalion of the Infantry Regiment.

[5] Following his marriage to Halina Bulczyńska he took up a new position in Poznań (Wielkopolska) and after the birth of his first son "Andrzej" on 28 November 1922, Grodyński was posted to Kobryń (now in Belarus) in Polesie.

Grodyński's second son, "Marjan", was born in Kobryń on 3 July 1925 and following his appointment as 'Poviat Starost' (Province Governor) he and his young family moved to Sarny (now in Ukraine) in Wołyń.

In recognition of his work Grodyński was decorated with the Gold Cross of Merit (Poland's then highest civilian award) shortly before the outbreak of war.

[6][5] On 1 September 1939, shortly after military operations commenced, Grodyński with his family drove to the railway station in Grudziądz to reach an evacuation point near Lublin.

[14] In 1941, following the signing of the Polish-Russian Military Agreement (30 July)[15][16][17] which granted amnesty to all those surviving in Soviet Russia, Grodyński immediately requested to meet with the NKWD authorities in Ałdan.

[6] After a two-week 'working visit' to Moscow, on 25 October Grodyński was assigned to the 6th Polish Army Infantry Division which was being formed in the town of Totskoye in Kazakhstan.

A few months later the entire 6th Division was transported through Hamadan to the territory of Iraq, where all the military units were deployed in the vicinity of the towns of Khanaqin, Quizil-Ribat and Kirkuk.

[18] The ending of the Second World War was devastating for Grodyński and other serving Poles who fought with the Allied Forces when much of Eastern Europe, including Poland, fell to Russian hegemony, thus robbing many of them of the prospect of returning to their homeland.

[22] Living in Balham, South London, Grodyński was one of the first members of the Polish Catholic Parish and of the White Eagle Club inaugurated in the area.
