Hi Bob, No, the Coffin book does not say if he and Ida were divorced or if she died etc.The only date on their entire entry in the book is his birthdate. Sorry I can't be of more help to you there. That is so interesting about the book illustrations, you might be right,...that could be one of his first published works. Thanks for sharing what you have about him too.Very intersting man...such a shame his life ended so tragically. Good Luck to you on your research.
