What if one of the sons of Dutch King William III lived? I guess it would have to be the last two because for the first one to live you'd need to change William III's personality. Assuming that whichever son gets the throne has male offspring and/or lives until WW I, Holland will be envolved into WW I due to the personal union with Luxembourg (assuming WW I happens on schedule). Because of this I imagine Von Moltke jr. wouldn't alter the Von Schlieffen Plan to avoid Dutch Limburg. And of course Wilhelmina never becomes Queen, butterflying away Juliana, Beatrix and Willem-Alexander.
