The book referred to is by George F. Willison, copyright 1945. Although it's out of print now, it must have been very popular, because I have often seen copies at used book sales, flea markets, etc. I have a copy myself, picked up at one of those sales, but I've never got around to reading it.

The full title is: "Saints and Strangers: Being the Lives of the Pilgrim Fathers & Their Families, with Their Friends & Foes; & an Account of Their Posthumous Wanderings in Limbo, Their Final Resurrection & Rise to Glory, & the Strange Pilgrimages of Plymouth Rock."
