So Marvel's Star Wars comics have often included material from the sequel trilogy into the OT era.
For example
-Poe's parents being recurring characters in the regular title
-Vader finding out about Exegol and the Final Order destroyers in DV, also a slight implication that Snoke might have been cloned from Luke's hand
-Knights of Ren being involved in the current "Hidden Empire" crossover
-Multiple uses of Canto Bight
And of course Holdo has appeared as a major character in the current "No Space" arc. The character did play a pretty big role in the Princess Leia novel which was released in part around "The Last Jedi"
What's interesting is that in this, Holdo and Lando have seemed to start up a relationship-or at least a small fling-after the two bunk together and Lando is worried he'll always be seen as a con artist and nothing more, but Holdo starts to see that he has potential to be a hero/good man and the two kiss.
Makes me wonder, it's established, although off-screen, that Lando had a daughter, Kadara, whose mother is unidentified. Kadara herself is taken by the First Order and presumably raised to be one of their Stormtroopers (There was some speculation that Janna was her but that's been dismissed) which was part of a larger FO campaign to target the former alliance. (Poe, the son of two former rebels, seems to have avoided it; and someone like Leida was presumably too old; Aftab "Junior" Ackbar also seemed to escape this). This all of course has it's greatest "triumph" with Ben Solo falling to the dark side.
So perhaps Holdo is the mother?
