It is mentioned in the Srimad Bhagavatam that in the period of the eighth Manu, the incarnation of the Supreme Personality of Godhead appears as the son of Devaguhya & Sarasvati.
सार्वभौम इति प्रभुः
स्थानं पुरन्दराद् धृत्वा
sārvabhauma iti prabhuḥ
sthānaṁ purandarād dhṛtvā
balaye dāsyatīśvaraḥ SB 8.13.17
In the eighth manvantara, the greatly powerful Personality of Godhead Sārvabhauma will take birth. His father will be Devaguhya, and His mother will be Sarasvatī. He will take the kingdom away from Purandara [Lord Indra] and give it to Bali Mahārāja.
The Sarasvati that is mentioned here - Is it Goddess Saraswati ? Who is Devaguhya ?
