It's possible that:
* The poems have different names. Double-check the titles or any other identifying information you might have.
* The author's name is incorrect. Verify the spelling of the author's name and check for any aliases or variations.
* The poems are not publicly available. They might be part of a private collection or unpublished works.
To help you find the poems, please provide:
* Any other information you have about the poems, such as publication dates, themes, or any other relevant details.
* Any additional context about where you encountered these poems. This might help to narrow down the search.
