Genealogy / Konstanty family search [7]

Hi,
This is my first time doing this so I hope everything is ok. I am researching my husband's father's family in Poland. His name was Jan Konstanty. For years we received letters from his brother who stayed in Poland. Now he has passed he have no contact. For my children, I would like to have a family tree and some understanding of the wonderful culture they came from. This individual joined the Polish Resistance Army and ended up living in England. My husband, Jan's son, met me when traveling over Kentucky back in the hitchhiking days of the 70's. Would anyone be able to help me with this connection? Thanks
