I have no idea. It doesn’t give everyone’s birthday. Broyles’ or Astrid’s are not mentioned but Charlie Francis’s is listed as June 22nd 1976.
Etta’s birthday isn’t mentioned either. It just says that she was 3 when the invasion happened in October 2015. So depending on what day the invasion actually was (the date was never mentioned just the month) her birthday has to be from late August/September 2012.
