Genealogy / Looking for the Chamerski Family [3]

Okay, hi people. I need some help pronto on this. I need to locate a family living in Gdansk, Poland. I'm going to list some names and if any of these ring any bells, please PM me.

Person I am searching for: Curtis Mark-Anthony Chamerski. (He moved to poland about two years ago)

This guy has been really hesitant with information, he has 4 sisters, an older one whose name I cannot recall and another one named Lauren Chamerski. I won't put the names of his younger sisters here. PM me.

All I have is his contact number but his number is switched off. He gave me his aunt's number for emergencies but try as I might, I cannot get onto her.

He told me his uncle works for a company that does ship/train repairs for cargo companies across Poland. Anyone have any clues what that company could be and does anyone know of a Mr. Chamerski that works there?

Curtis told me a brief history of his family... after the war, they were destroyed. His father's named is David Mark-Anthony Chamerski. He is deceased now though.. does anyone know this man?

I'll be grateful for any information about the Chamerski family in Gdansk. Thanks in advance.
