You need to register the copyrights at www.copyright.gov. You will then be able to sue for copyright infringement. You will prevail if you can demonstrate to the court using the rules of evidence that: 1) you created the poems; 2) you made them publicly available; 3) the funeral homes had access to the poems that would allow them to copy the poems.
If the poems were copied before you registered your trademark, your damages may be limited to reasonable licensing fees.
