Final answer:
Mercy Otis Warren did not have a son named James Warren; the reference to the birth of a son in June 1688 pertains to James II of England, not Mercy Otis Warren.
Step-by-step explanation:
Mercy Otis Warren, a distinguished figure in American history and an advocate for women's rights, did not have a son named James Warren; it appears there might be a mix-up in the historical figures being referenced. Mercy Otis Warren was noted for her active opposition to British reforms and her significant contributions to the literature of the American Revolution, which included a three-volume history published in 1812.
However, the references to James and the birth of his son in June 1688 relate to James II of England, whose wife gave birth to a son that caused political and religious upheaval in Britain.
