I was looking with Google for my name (mieraja) and so I came here.
Mieraja does mean nothing in Dutch, its only a name. It's also a unique name, it doenst exist anywhere else..(They do a search for me, thats why I know this)
The only thing it stands for is in Polish: They die younger (my name stands on package sigarettes..)
I think that is what you mean?
