Might mention copyright law and IP in regards to WS' plays being pirated (e.g., first (bad) quarto of Hamlet. Cf. today and digital media and the law.

WS had twins named Hamnet and Judith.

WS' father was probably a crypto-Catholic.

Weren't the sonnets more highly regarded during WS' times than his plays?

Ben Jonson's "little Latin and less Greek" in re WS' scholarship.

Of all his plays, only The Tempest may be based on an original (with WS) plot. All the rest are from well-known sources.

The first critic to mention WS and write about his plays was Thomas Rhymer who basically panned WS on theoretical grounds.

I'm sure there are more, but that's my tuppence farthing.
