Targaryens

I am trying to workout timelines for this lot.  The Story of the Targaryens book, Fire and Blood, came out in 2018. I have not read it and do not own a copy. In the case of Game of Thrones, I read all the books before the story finished on TV however as we know, it departed from the books storyline and to complicate it further, the last two books are not yet published, some 17 years after the earlier volumes. GRRM has promised the next one this year.  Back to the Targaryens, that book was set 170 years earlier and published before the later story has been published and now the earlier story has made it to TV as well.  Confused?  Should I get the 2018 book and will the TV version matchup?  

The 170 year gap will ensure no characters from GOT will ever be born in time to feature in The House of the Dragon.  The oldest one from GOT I can remember is the blind Maester in the Night's Watch who was Aemon Targayren. He may have been 100 yar old but that still leaves him 70 yar short of the Targaryen storyline.  Laura gave me a copy of the complete history Westeros and I have got the lineage from it below.  The only other printed link I have read is the short stories about Egg (Aegon the unlikely) & Dunk.  AegonV was Aemon's younger brother and these short stories are about Aegon as a boy and would be around 100 years before  GOT.  Aegon was the unlikely because he was the fourth son of a fourth son but still took the throne.  Maybe this story will also be told.

This photocopy doesn't do the detail justice. GRRM eventually had to commit this to a database
