The "mir" element presumably is the same as in Boromir's, his brother's, name,
which means "Steadfast Jewel" (mir = "jewel"). There is a verb in
Sindarin, fara-, which means "to hunt," but I haven't gotten any farther than
that.

From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.
