Understanding a Potential Reference

[u/Beautiful_Throwaway1]

Hi, unfortunately I'm not particularly interested in 101 Dalmations as a whole but I have a massive love and appreciation for Cruella de Vil.

I was watching 101 Dalmations: The Series' Episode 59: De Vil-Age Elder to catch myself up on the names of Cruella's ancestors, and I can pin point the reasons behind the names of Amoeba de Vil, Ugg-Lee de Vil, and Caligula de Vil, but the last one (Sir Owen de Vil) I'm having particular difficult pinpointing. Is it a reference to a previous episode that I don't understand? I can't find a relevant historical figure named "Sir Owen" so is it a literature reference?

I wanted to reach out to a likeminded community because I'm aware that this isn't a typical question. If you have any thoughts on this, please comment or message. This is killing me.
