Ariel's mom was in Peter Pan and was murdered by Captain Hook.

Disney is no stranger to easter eggs, and this one seems to be more than 30 years in the making. The mermaids in Peter Pan may not be super memorable, but there is one mermaid that sticks out more than the rest, a young red head who bares a striking resemblance to another famous Disney mermaid. While we never meet Ariel's mother in The Little Mermaid, in Ariel's Beginning we learn that her name is Athena, and the mermaid in Peter Pan is never named, meaning her name could easily be Athena. It is also revealed that Athena was killed by pirates, and the mermaid in Peter Pan have a less than cordial relationship with Captain Hook and his pirates, could be be that Hook killed Ariel's mom?
