About the author
Available catalog records identify J. D. Williams as James Douglas Williams, born in 1846. He is credited on Project Gutenberg as the author of The Squirrel's Pilgrim's Progress, and the Internet Archive also lists school-oriented works under the fuller name James Douglas Williams.
The surviving online record is fairly sparse, so only a small outline can be confirmed with confidence. His known books suggest a writer interested in both children's storytelling and language instruction, including titles such as Reading Conversation Composition and Practical Studies in Grammar.
Because biographical details beyond his birth year are not clearly established in the sources I found, it is safest to remember him as a lightly documented author whose work appears to have been aimed at students and young readers.
