The only place that that could fit is year 8, in the first half, given that the second one is filled with something like **** & *** RETURN EARTH if I'm not mistaken (I'm not sure about the Earth part, to be honest). I can only read OF in the middle of the first item in that year for them.
With all that's happening in Year 9 (the year Jon's born), I wouldn't be surprised if they are going hiden within that same year and that's implied from one of the other 3 items.
