Genealogy / Żeglicki genealogy [3]

I'd love to research my family name - Żeglicki

Here's what I know.

Grandfather: Zbigniew Zeglicki, born 24 October 1920 in Rzeszów, Poland, died 19 November 1989 in the UK
Parents: Kazimierz Żeglicki, born 4 February 1895, died 7 February 1958 and Honorata Kowal
Paternal grandparents: Pawel Żeglicki and Bogumiła Tokarzewska (Pawel may have married twice, second wife called Maria?)
Maternal grandparents: Mikolaj Kowal and Franciszka Gruszecka
Maternal great-grandparent: Maria Rerutkiewicz (born c.1843 died c.1940)

Grandmother: Kazimiera Sudacka/Sudecka, born 13 January 1923 in Chełmno, Poland, died 27 June 1993 in the UK
Parents: Jozef/Jozej Sudacki/Sudecki and Zofia Kloniecka (born 12 February 1903, died 23 January 1973 in the UK)

This is all my family knows.

I do have a surviving great aunt (my grandfather's sister) Maria Stenzel nee Żeglicka, who is now 90. Her husband was Leon Arkadiusz Stenzel (12/1/1913-11/10/1996). One of her daughters, Bogumiła Stenzel is my godmother. Her husband is Tomasz Maramaros. Tomasz's mother is Teresa Mycielska - I can find her ancestry very easily... follow this link: sejm-wielki.pl/b/dw.59640

Any help on my side of the family would be great! Thanks ;)
