On the judgement day no relatives would recognize one another, no pleading, begging would work. Even if you offer them gold, diamonds, money but your burden would not be carried out by anyone. Everyone would be standing alone with their book of deeds.
“And no bearer of burdens will bear the burden of another. And if a heavily laden soul calls [another] to [carry some of] its load, nothing of it will be carried, even if he should be a close relative. You can only warn those who fear their Lord unseen and have established prayer. And whoever purifies himself only purifies himself for [the benefit of] his soul. And to Allah is the [final] destination.”
Quran(Surah Fatir, 18)
