Is there a Japanese name that can be written using the kanji for both cliff and ford?

From my understanding kanji have multiple pronunciations depending on how they combine, and names don't always follow those rules.
I've been trying to combine the kanji to get a name, but unfortunately my knowledge of Japanese is high school level at best.

I don't think the kanji for cliff, which is 崖, is often used in a Japanese name.

So I can't thing of any name as you said.

Yes

石渡 (Ishiwatari, rock+ford) is close, as a family name instead of a first name. There's 岩渡 (Iwatari, crag+ford), but that's more of a location than a family name.
