On this account, when Rukmiṇī’s grandson Aniruddha was to be married, Rukmī offered his granddaughter Rocanā to Aniruddha.

Krsna Book 61:

Although Rukmī was a veritable enemy of Kṛṣṇa, he had great affection for his sister, Rukmiṇī, and wanted to please her in all respects. On this account, when Rukmiṇī’s grandson Aniruddha was to be married, Rukmī offered his granddaughter Rocanā to Aniruddha. Such marriage between immediate cousins is not very much sanctioned by the Vedic culture, but in order to please Rukmiṇī, Rukmī offered his daughter and granddaughter to the son and grandson of Kṛṣṇa, respectively. In this way, when the negotiation of the marriage of Aniruddha with Rocanā was complete, a big marriage party accompanied Aniruddha and started from Dvārakā. They traveled until they reached Bhojakaṭa, which Rukmī had colonized after his sister had been kidnapped by Kṛṣṇa. This marriage party was led by the grandfather, namely Lord Kṛṣṇa, accompanied by Lord Balarāma, and it included Kṛṣṇa's first wife, Rukmiṇī, His son Pradyumna, Jāmbavatī’s son Sāmba and many other relatives and family members. They reached the town of Bhojakaṭa, and the marriage ceremony was peacefully performed.

Pradyumna happened to be the eldest son of Queen Rukmiṇī, and he inherited all the qualities of his great father, Lord Kṛṣṇa. He married the daughter of his maternal uncle, Rukmī, and from that marriage Aniruddha was born. Aniruddha was so powerful that he could fight against ten thousand elephants. He married the granddaughter of Rukmī, the brother of his grandmother Rukmiṇī.

Krsna Book 90:

Among Kṛṣṇa's greatly powerful sons, eighteen sons were mahā-rathas. The mahā-rathas could fight alone against many thousands of foot soldiers, charioteers, cavalry and elephants. The reputations of these eighteen sons are very widespread and are described in almost all the Vedic scriptures. The eighteen mahā-ratha sons are listed as Pradyumna, Aniruddha, Dīptimān, Bhānu, Sāmba, Madhu, Bṛhadbhānu, Citrabhānu, Vṛka, Aruṇa, Puṣkara, Vedabāhu, Śrutadeva, Sunandana, Citrabāhu, Virūpa, Kavi and Nyagrodha. Of these eighteen mahā-ratha sons of Kṛṣṇa, Pradyumna is considered the foremost. Pradyumna happened to be the eldest son of Queen Rukmiṇī, and he inherited all the qualities of his great father, Lord Kṛṣṇa. He married the daughter of his maternal uncle, Rukmī, and from that marriage Aniruddha was born. Aniruddha was so powerful that he could fight against ten thousand elephants. He married the granddaughter of Rukmī, the brother of his grandmother Rukmiṇī. Because the relationship between these cousins was distant, such a marriage was not uncommon. Aniruddha's son was Vajra. When the whole Yadu dynasty was destroyed by the curse of some brāhmaṇas, only Vajra survived. Vajra had one son, whose name was Pratibāhu. The son of Pratibāhu was named Subāhu, the son of Subāhu was named Śāntasena, and the son of Śāntasena was Śatasena.
