A couple more that probably don't qualify but for conversation..
Bebe Buell (not on film though) - Liv Tyler
Colleen Farrington (not on film though) - Diane Lane
Jerry Hall - Elizabeth Jagger
Bianca Jagger - Jade Jagger
Cheryl Ladd - Jordan Ladd
I made the list based on hotness AND NUDITY. Eva Amurri and Susan Sarandon would have been on if Eva had shown her outstanding breasts. Same With Melanie Griffith and Tippi Hedren. Tippi was never nude, though she had a nice bra and panty scene in The Harrad Experiment. Mia and Margret O'sullivan is a great call!
How about Mia Farrow & her mother, Margaret O'Sullivan. In Tarzan, Jane dives from a tree branch to the water below, but Tarzan is standing on her dress. Jane hits the water, without the dress. There is an extended scene of Jane swimming underwater in the buff. This scene surely contributed to the Hayes Code.
Mia Farrow was nude in RoseMary's Baby. Don't know if any of Mia's daughters are actresses. Then you could have 3 generations.
