Completely normal names flagged as disallowed

Just wanted to give Count Vladislaus Straud IV a daughter, her name is Sabine Straud and she has a mix breed cat named Hershey. Trying to upload the household to the gallery I had to change the name of the household to just Straud as it was being marked as too long. Now it won't allow me to upload as somewhere it contains a banned word. I haven't changed the household description or anything other than I have stated. Not sure what I'm doing wrong here?
