In Hinduism Family are of paramount importance and sacred.

”अयं बन्धुरयं नेति गणना लघुचेतसाम् | उदारचरितानां तु वसुधैव कुटुम्बकम् || ”ayaṁ bandhurayaṁ nēti gaṇanā laghucētasām | udāracaritānām tu vasudhaiva kuṭumbakam ||

Discrimination saying “this one is a relative; this other one is a stranger” is for the mean-minded. For those who’re known as magnanimous, the entire world constitutes but a family. – Mahōpaniṣad– VI.70-73, book of Hindu astrology, 3000 BCE
