So nephew is a son of my brother/sister
In english its single word, but in other languages it may be 2 words.
Example:
<MyNephewLost.stages.my_nephew_lost.label>My nephew1/nephew2 {0} lost</MyNephewLost.stages.my_nephew_lost.label>
Can you extend that to something like this:
<NephewOfMyBrother.label>Nephew1 <-- nephew borned by my brother
<NephewOfMySister.label>Nephew2 <-- nephew borned by my sister
Or there already is a way to do it?
