What does it mean?

Other items to include:
WML²
Owee
Caden
Mason

These 4 words need to be incorporated into the tattoo.

Just to give a little bit of context to the things I wanted to include in the tattoo.
I'm an immigrant to Canada. I was born in Poland. Our immigration path from Poland to Canada took us through Germany (our actual first stop was in Copenhagen (Denmark), then Dusseldorf (Germany) then we landed in Grande Prairie (Canada), I now live in Calgary (Canada).
WML² is both my and my wife's initials (thus the squared), Owee, Caden and Mason are names of my sons.
Alcro Logo is my company, Oilers is my Hockey Team, Polish and Canadian flags are me being a Canadian born in Poland.
Hope this helps.
