Considering how Cadence's lineage belongs to the Crystal Empire royalty, not to mention that she was also young when Twilight was a filly, it's almost certain that they don't share any relatives.

I would say that, once the Crystal Empire got cursed and vanished 1000 years ago, Celestia and Luna took the current royalty as an extended family until they could recover their empire.
