That is quite the plot hole, don't you think? Since niece means she's DIRECTLY related to her by Celestia's brother or sister. The "no other siblings" issue was never address in the show so their siblings could make an appearance in flashbacks, etc, since the two sisters are immortal. Their siblings would have to be too.
