Take this as rumor for now but I’d also heed that potential spoiler warning wisely! It’s a doozy if it turns out to be true so read no further if you’re sensitive these things.
According to ThePlaylist.net the character Katherine Waterston is playing in Alien:Covenant is none other than Ellen Ripley’s mother! Now you could just write this off as strange and/or silly rumor but the fact that 20th Century Fox demanded that Playlist remove the rumor and now it’s gone does lend some credibility to it. No word on if the character is named Martha.
Of course Covenant is the followup to Prometheus which was a prequel of sorts to Alien. Directed by Ridley Scott (“Alien,” “Prometheus”) from a screenplay by Jack Paglen (“Transcendence”), Michael Green (“Green Lantern”) and John Logan (“SPECTRE”), the “Alien” prequel stars also Michael Fassbender (likely reprising Prometheus cyborg David), Amy Seimetz, Billy Crudup, Jussie Smollett, Danny McBride and Demián Bichir. Covenant will hit theaters August 4 2017
