Genealogy / Anyone know my dad, Ignacy Laszkiewicz? [5]

Greetings from Devon in England.
I am here to trace my dear departed father's roots. Whenever we asked him about Poland he just smiled and gave really vague answers or just changed the subject!

I've just broken my leg so have lots of time to unearth the truth!
My only clues are:
Name: Ignacy Laszkiewicz.
Parents' names: Antoni and possibly Zeta.
Born: 1925 in Vilnius (Vilna?)
Any help/suggestions would be greatly recieved.
Sprout.
