I didn't know that Sylvia Meals (Apollo's wife) passed away over 10 years ago?
It's hard to find online, a whole lot of information about her. She didn't really have a prolific Hollywood career. According to IMDb, she only has four acting credits from 1979-2007.

Carl Weathers did mention her at least once on Twitter:
