No. In the commonly cited Jain historical sources, Vastupāla is described as having one son, Jayantasimha (also called Jaitrasimha), from his wife Lalitādevī. ( jainqq.org)
Explanation
The reference to “two sons” belongs to Candaprasada, an ancestor in Vastupāla’s lineage, who had two sons named Soma and Sura. That is not Vastupāla himself. ( wisdomlib.org)
Spiritual Understanding
In Jain historical tradition, Vastupāla is remembered more for his dharma, charity, temple-building, and support of Jain religion than for family details. His son, Jayantasimha, is also mentioned in the tradition connected with his family’s later activities. ( jainqq.org)
Takeaway
So the short answer is: Vastupāla did not have two sons in the standard Jain accounts; he is usually said to have one son, Jayantasimha. ( jainqq.org)
