The ill-fated king of Poland and later duke of Lorraine only had two daughters, Anna (b.1699, d.1717), and Maria (b.1703), who became queen of France, that I'm aware of. Maria seems to have either been deeply grieved by Anna's death or resentful of Anna being their dad's favourite child, since her husband, Louis XV, was surprised to find out that she had had a sister after being married for so many years.
Now, what if Stanislas had had a son? Born between 1698 (when his parents married) and 1703 (since they had no children after Maria, even though Mrs. Leszczyński was only 23, seems to indicate that there may have been a problem in that department - especially considering Maria's bountiful issue). Also, I can't seem to find a mention of even bastard issue for Stanczyk Sr, so the problem might have been either side.
I would imagine that this boy, let's call him Stanczyk Jr, would make things like Leszczyński getting the duchy of Lorraine as a lifetime grant or maybe him being deposed as king of Poland to start with, rather more complicated than OTL. And if Stanislas doesn't wind up deposed, what does this mean for the PLC's future with no PU with Saxony? Would this be the case (not getting deposed)?
