Sorry Tamara, I don't have an iris that looks like this and it's not ringing a bell. As a start, have you tried browsing the gallery at the Historic Iris Preservation Society's webpage? https://www.historiciris.org/

Fritz' site.......Bennet Iris garden , or http://www.irisparadise.com/Ir... .......is a good source of information, too. Both site have some "tips" on identifying iris , and, are my "go to" places to search for ID.
