Reliance on birth time record on a document without question or verification is to act as if such a non-astrological document holds more information about the native than that person does with their body or life. Reliance on word of mouth or memory from the person (especially since Madonna is not an astrologer) creates a weak astrology of presumption. The body cannot lie. It reveals the essence of the person when viewed along with their actions.
Madonna's pictures from her childhood and 20s show a clearly full rectangular/squarish facial outline allowing for a fixed sign on the Asc, not a mutable one, especially not Virgo. Plus the Virgo Asc + Moon personality is in complete contradiction to her flagrant outward behavior and performance.
Theoretically Aquarius, a fixed sign, could be on the Asc, but it would not predispose her whatsoever for the love and care of children (which is far more natural to Leo/5th types). Plus it would create an entirely different MC/IC axis with MC in late Scorpio/early Sag. The MC is really important in a celebrity careerist and could be the only way to track them. Check the MC transits and progressions for major public/career events like record releases, book releases, these hitting the best seller lists, etc. I've already validated this chart sufficiently enough using other events, but let's do this for the doubters...
Pardon me, I forgot to post the validating progressions with my chart attachment previously.

---------NOW FOR CAREER EVENTS----------
Debut album, "Madonna" released 27 July 1983. This will involve MC (29ARI05 / 11N09)and probably 5th cusp/ruler.
TRANSITS:
* Uranus BQ n MC orb<0*07'>a - when an artistic endeavor gains distinction this planet is very often transiting the MC.
* Neptune sesquiquadrate n Asc <09'>a
- Jupiter quincunx MC <2*>
- Saturn opp MC <1*>
- Neptune in 5th house trine MC <2*>
- Pluto opp MC <2*>
PROGRESSIONS:
- pr Asc sextile pr Jupiter (ruler of n 5th) <01'>a
- pr Asc semi-sextile n Venus <07'>s
- pr Mercury trine n MC <07'>a
- pr Jupiter square n Venus <07'>s
- pr MC quincunx n N.Node <02'>a
"Ray of Light" was released 3 March 1998. Again MC, and 5th = creative output.
TRANSITS:
- Uranus opp Asc <1*>
- Pluto trine Asc <4*>
- Venus square MC <-1*>
- Mars semi-sextile MC <-1*>
- Neptune square MC <2*>
PROGRESSIONS:

- pr 5th cusp 12CAP48 quincunx n Uranus 12LEO41 <07'>s
- pr Venus square n Saturn <02'>a
- pr Neptune conj pr Jupiter <03'>s
"Ray of Light" won four Grammy Awards on 24 Feb 1999. This event will show MC aspects for the honors bestowed. (Using 25 Feb 0:00 UT for eve timing in USA).
TRANSITS:
- Uranus [17S13] ContraParallel Asc <0*02'>
- Uranus still opp Asc <2*>
- Saturn conj MC <-1*>

- pr Venus [5N08] Parallel n Mercury [5N03] <05'>a
There should be no doubt left in anyone's mind this is Madonna's correct natal chart. If there is, do further in-depth study on rulerships, especially the Asc/1st house rulership of body/personality. I recommend The Rulership Book, by Rex Bills, as well as The Rising Sign Problem, by John Willner (for Asc/body/face).
When it comes to verification, use the aspectarian. All these aspects listed were taken from astrodienst's pdf data sheet aspectarian. Even "minor" aspects count for major events. Those aspects aren't really minor anyway, especially when they involve slower moving outer planets.
