All Astrology is nonsense. That said:
(a) there is minor variation in human temperament (personality0 given the season of birth, because of the remaining biological variation in hormones given our ancestry of fall mating and summer birth. (b) there may be some seasonal behavior caused by mothers bodies during different seasons, and some effect of the birth season on initial formative infant experience, (c) There is no other behavioral difference we are aware of other than that cause. (d) Yes the rest is coincidence because there is a well understood human cognitive bias to see patterns where they do not exist.
