So this has bugged me lately...

My brother and sister do not have kids.

My husband's brother has 2 daughters, the other has a step daughter.

Now the step daughter I have met twice, and really know nothing about, and don't consider her my niece as such.

But the other 2 girls are Charlotte's cousins, I think of them as my nieces, but is that actually right? They were born after DH and I were together, so am I aunty? We refer to their parents as Charlotte's aunt and uncle (they are not married though).

Are they our nieces, or my husbands?



(Oh yes, can you tell? I am into solving the crucially important mysteries of the world here...)
