Here are some possibilities to consider:
* R.H. Macy: This is the name of the founder of Macy's department store. While he may not have written any books, he was a significant figure in American retail history.
* R.W. Macy: This could be a shortened or stylized version of a different name. It's worth searching for authors with similar names to see if you can find the right one.
* A different spelling: It's possible the author's name has a slightly different spelling that you may not have noticed.
To help me find the correct author, please provide any additional information you have, such as:
* The genre of the book: Is it fiction, non-fiction, poetry, etc.?
* The title of the book: This would help me narrow down the search.
* The approximate year of publication: This can help rule out authors from different periods.
Once I have more details, I can help you find the author you're looking for.
