Masons' Children or Grandchildren:

H. P. Lovecraft - author

http://www.freemasonry.bcy.ca/biography/lovecraft_h/lovecraft_h.html

Edgar Rice Burroughs' father was a Freemason http://www.erbzine.com/mag11/1133.html

Jules Verne ? https://www.innertraditions.com/the-secret-message-of-jules-verne.html

With so many authors sharing a connected theme in the numerous books and a connection of many author either being Masons or children/grandchildren of Masons. I think cannot be mere coincidence.
