My great grandmother *Hedvig-Jadwiga-Hedwig-Hedvigis Świątek" which I cannot research further

Question

Dear genealogists, 

My family tree sometimes leaves me frustrated when I early on hit a wall. 

My maternal grandfather's mother,

 Hedwig/Hedvigis/Jadwiga Świątek, 

born 12 Aug 1906,
died 28 Nov 1972, 

lived and died (?): Zborowo, Powiat Poznański, Wielkopolskie, Poland.

born: ? Probably nearby; buried in Junikowo Cemetery (Poznań) with her husband

her husband:

Michael Bakowski

born 12 Sep 1902, [location unknown]
died 28 Mar 1974, [location unknown]

also known in Polish as Michał Bąkowski, married Jadwiga

they lived in Zborowo, Powiat Poznański, Wielkopolskie, Poland

They had at least 2 sons and 1 daughter:

Włodzimierz Bąkowski 

B. 1936 in Zborowo, Wielkopolskie, Poland.
D. 2021 in Leszczyny, Dolnoslaskie, Poland.

and my grandpa:

Seweryn  Bąkowski

Born 28 Dec 1937 in Zborowo, Wielkopolskie, Polska

Son of Michael Bakowski and Hedwig Świątek

Husband of Bogumiła (Mańczak) Bąkowska 

Died 19 Sep 2010 at age 72 in Poznań, Wielkopolskie, Polska

Since I don't know how to proceed with this roadblock, would you be able to assist me with pushing my tree further?

Comments

I have added the Poland tag in the hope this help to attract the attention of someone who may be able to help.

I would also add Germany since up to 1919 that was Prussia.
