* A misheard or misspelled name: Perhaps you've encountered a different group of poets with a similar name. Could it be "Brahman poets," "Brahim" with a different spelling, or a different term entirely?
* A local or regional group: It's possible that "Brahim poets" refers to a specific group of poets from a particular location or time period that has not gained wider recognition.
If you can provide more context, such as the time period, region, or any other information you have about these poets, it would be easier to determine their identity.
