Bruce Charlton, over at The Notion Club Papers, offers a link to a .pdf by Professor Joel Heck of Concordia University, Texas. It’s “a detailed, birth to death chronology of both Jack and Warnie Lewis.”

I’ll give Bruce the hand-off, instead of linking to it directly: http://notionclubpapers.blogspot.co.uk/2017/07/chronologically-lewis-by-joel-heck.html
