- - Uranus rises before her Sun (makes her special and is frequent in the charts of oldies. However, it takes more than one indication...)
- - She has 5 positions in air signs. Air signs take it more lightly and seek contact. That is a big help on the way.
- - Uranus in Aquarius is in aspect with the midpoint Sun/Jupiter (in Sagittarius). Sun-Jupiter-Uranus combinations are frequent among centenarians.
If we had her time of birth, we'd know more, but those three together helped her to reach this age for sure...(And genes of course)
But why did she marry now? We see transit Uranus semi square natal Sun for the news and transit Pluto conjunct her Venus for the strong desire to get married. Progressed Venus inconjunct Progressed Jupiter is typical for a celebration (and the inconjunction for overdoing it a bit). Proressed Mercury square Mercury doesn't seem to have anything to do with it, unless Mercury rules the 7th house of marriage (and we don't know about that). However, I think that the main point is that her Moon is in Libra, showing the need to be together and have some company!
Here are the charts of the day of her birth, with transits and progressions and the the progressed chart with transits.
