We know he was born on 20 Oct 1915 in Wlodzimierz, Wolyn, Poland (from his 1962 US petition for naturalization along with his second wife).
We know from a newspaper report (page 6 of the 31 Aug 1945 Peterborough Standard) of his 28 Aug 1945 Peterborough marriage that he was
"Paratrooper Wladyslaw Baranowski, of a Polish unit [who] came on shore leave and returned immediately to Germany, where he is serving with the B.A.O.R."We know nothing about him between those dates, but following the Wikipedia breadcrumb trail of
BAOR,
BLA,
21st Army Group,
Polish I Corps, I ended up at the
1st Independent Parachute Brigade (Poland), and somehow (my browser history doesn't tell me how) got to the fact that
RAF Spitalgate, about 20 miles from Peterborough, was
"the training and point-of-departure for the Polish 1st Independent Parachute Brigade during Operation Market Garden.", which makes me think (educated guesswork) that he met his bride-to-be while training there.
