Genealogy / Searching For Blaszkowski Relations [3]

Hi I am interested in getting to know relations of mine that I have never met before.
My Grandfather Leonard Blaszkowski moved to England from Tuchola Poland after WW2.Sadly he passed away this year aged 83, would have been 84 this November. I know he has two brothers, Marek (alive I believe) and Bronislaw and possibly more, he also had two sisters, one who is still alive and older whos name does not come to mind. I think he grew up on a farm and his mother a barrister (that could be wrong).

If any of this information sounds familiar please reply, thank you.
