Planning a timeline where James II and Mary of Modena die in 1687, thus meaning Mary becomes Queen, there is no Glorious Revolution and no Bill of Rights and Anne has surviving issue.
Her children:
Mary (b.1685)
Anne Sophia (b. 1686)
James (b.1687)
William (b. 1689)
My query is this, who could these children marry?
For James I was thinking Maria Josepha of Austria, daughter of Emperor Leopold by his third wife. Perhaps as part of an alliance during the War of Spanish Succession.
Mary could perhaps marry Frederick IV of Denmark?
Anne Sophia could perhaps be married to Frederick William of Prussia? or maybe George II of Hanover, though with Anne's dislike of George I I doubt it.
