Only reason I'm thinking Isis and Osiris is because Osiris is the father of Horus, and usually when I see the male and female figures together like that it turns out to be the two of them. I think the representations are off or 'stylized' because it was created with the uneducated american or european audience in mind.

I'm also highly doubting the 200 year old story. The blue green in it screams chemical dye at me, which they wouldn't have had 200 years ago. Also, remember anything associated with ancient Egypt became very popular in the 1920's with the discovery of King Tut's tomb. It influenced fashion, home furnishings, and architecture for years afterward.
