 Next in line after the king's children was his sister Margaret Tudor, and her children, but their place in the succession was not secure – Henry would later exclude them by the Second Succession Act (1536), and by his will.Next in line after that came the Duchess of Suffolk and her son Henry Brandon, who during his own lifetime (he died before Henry's son Edward was born), was the only person in the line of succession who had the twin qualifications of being male, and English.However, he died at the age of ten or eleven, in Southwark.
