Well, if my interpretation of your south node story is at all historically correct, you were a gypsy previously. And you definitely share some karma with them. Even if the details of your past life(s) are different than what I just got out of it, that a gypsy's story can fit the picture shows that you have some karmic similarities.
What I didn't get around to saying earlier was why I thought you might have faced the Holocaust. Several factors here: first, Pluto squares your south node and all the planets conjunct it. A square from Pluto typically means very harsh circumstances that you were up against. It often indicates the worst of the worst of human behavior. With that in square to your south node, you might have been a victim of, for instance, sexual violence, or constant abuse, or a crazed serial killer... or genocide. In Sagittarius, we have a couple of indicators: first, Sagittarius stands for morals and ideals; in a south node context, that tends to mean fanaticism. The "Pluto" adversary you had appears to have been motivated by ideals and fanatical about them. Nazism certainly fits that picture. (As do other attacks against the Romany that have happened in the past.)
Secondly, Sagittarius itself is considered the sign of the gypsy--in the sense of a person who moves around and experiences lots of different things. And its ruler, Jupiter, is co-ruler of your south node and conjunct it. I wouldn't ordinarily take an interpretation this far, but if your south node's ruler squares your south node, it means you hindered yourself in some way. You don't have a square to your south node from either of its rulers, but you do have a square from a ruler's other domicile. To me, that suggests unwittingly being in your own way--such as being persecuted for who you were. You didn't cause that and couldn't prevent it (a square from your south node ruler, in contrast, would suggest the situation was at least partly your fault), but because of who you were, you were faced with that situation.
And then there's the house placement of your south node and one of its rulers. Eighth house has a very wide range of indicators, and in a south node context, we typically read the worst ones. Death, extreme edgy and dangerous situations, horror... a south node eighth house, especially one squared by Pluto, can easily indicate that you lived through that.
You also have a couple of supportive aspects: sextiles to Neptune from the moon in Aries in the ninth and Mars in Pisces in the ninth. That indicates a couple of things (people and/or circumstances) that supported you in that situation and helped give you your sense of identity. From that combination, I get the picture that you were a resistance fighter. That matches the history: there were many Roma involved in, and leading, resistance movements against the Nazis, and not just on their own behalf, either. Since your Mercury/Sun/Jupiter conjunctions with your south node strongly suggest a leader, war leader leaps out at me. Aries suggests bold and direct confrontation, while Pisces a more behind the scenes picture: guerrilla warfare, plotting. It looks like you were involved in both kinds.
Moon suggests a motive of protecting your children and saving your people; Mars suggests a real fighting spirit. Ninth house could again indicate Gypsies themselves, or lots of travel, or that this experience was self expansive for you, or all of the above. Since your current life moon is in Aries in the ninth, I suspect you have a strong desire for adventure and challenge, and that you find that experience expansive and rewarding. If you had similar feelings in that life, participation in the resistance could have felt like an exciting adventure, as well as being what you had to do.
