Wow, 4 citations. I feel happy for Lynn that she ended up doing a lot more impressive work, but definitely this should be restored to its proper place in the history of computing.
Something doesn't quite compute here though - according to Wikipedia after she announced her intent to transition Lynn was fired in 1968, but this paper was from 1966 - https://news.ycombinator.com/item?id=40650635 also does not have any information. Maybe at least someone shielded her for some time?
Also Francis Allen seems to have worked on the same project at IBM - she mentioned there were works by other women that other people (Turning award winners IIRC) took credit of - could Lynn's work be one of those? Really hope Fran and Lynn would at least knew each other.
