An associate of Paweł Stalmach (cs), who founded Gwiazdka Cieszyńska, he was also a friend of Józef Londzin (pl) with whom he shared the early vision of Cieszyn Silesia joining Galicia in a new Polish state independent of Austrian rule.

After completing his schooling Andrzej attended universities in Kraków, Graz and Vienna, then moved to Cieszyn Silesia due to his keen interest in Polish affairs centred in that region.

In 1887 "Jędrzéj" became a member of the Czytelnia Ludowa which was a Polish cultural society which facilitated public access to reading materials[6] and political interest that had been furthered in his university studies was expressed through his editorship of Gwiazdka Cieszyńska, from 12 January 1889 to 7 June 1890.

On 14 June 1890 fr Józef Londzin, in his first editorial on taking over from Kusionowicz, made no direct reference to this patriotic call by his predecessor but informed readers that he had been entrusted by the ‘Catholic hierarchy’ with the publication’s editorship before then making his own plea for the Polish nation and people of Silesia to guard against the forces of liberalism and Germanisation.

[8] While Kusionowicz was the editor, Gwiazdka Cieszyńska had continued to espouse the ideals of Paweł Stalmach in advocating support of many social causes ranging from improving the welfare of the poor to progressing literacy and education levels, especially among the ethnic Poles in Silesia and Galicia.

This career progression followed the birth of his son, Bogusław Jan Sylwester, on 19 August 1892, but on 28 April 1894 tragedy struck in Grodyński's personal life when he lost his first wife Anna (Vesnicky Polášek by adoption) who at only thirty years of age died from tuberculosis.

[16] The early years of the Second Polish Republic placed onerous demands on Poland's judiciary which in turn reportedly[17] led to a high mortality rate amongst those who chose to keep working in the service of their country rather than retire.

The funeral procession reflected his local, regional and national standing, with fellow judges, six priests and representatives across all levels of society, including the military, led by his close friend fr Józef Londzin.

[32] After assignments in Kobryń (now in Belarus), Sarny, Świecie, Toruń, Stanisławów and Kałusz (now in Ukraine) Stanisław was appointed Starost in Grudziądz prior to World War II and before his subsequent deportation with his wife and two young sons to a Soviet labour camp near Aldan in the Yakutsk region of Siberia.
