Well, here's an interesting link of celebrities with this placement.
http://www.astrotheme.com/celebrites/jupiter/m12/1.htm
The one that stood out was Winona Ryder, who has the same placement as you. I would say say that's a good example of what I was saying above. Took some quick notes:
MLK --jup in tau...rules voice/throat..Huge voice, religious.
Obama jup in cancer...blessed with good family, mother was special..women in life important. plus big house. very big house.
Jennifer-Lopez--jupiter libra...blessed with grace and beauty (and booty..)(sorry had to)
George Clooney..aqua..detached, cool..guardian angels friends? secret group/society? (also had big movie with j-lo)
Elvis...jupiter in scorpio...sex appeal was his saving grace..with jupiter ruling asc,he put what was hidden up front, his pelvis, and tv tried to make it hidden again
Jennifer Aniston..jup in libra..knew it! blessed with beauty and a lil booty, grace and charm
Sandra Bullock..Taurus..throat..Interesting voice, but she seems to have a little adams apple?
Katie Holmes..leo..acting ability, dramtatic, stage, performing
Bono..capricorn..has been to the white house..extremely into charities..very serious person..guardian angels ppl in high places, authority figures.
Tom hanks...virgo..very humble.down to earth is his saving grace.
Cindy crawford..gemini...saving grace is youthful spirit..kept beauty for a long time.
David beckham..aries...athletic ability, sex appeal to opposite sex, which mars rules. so models as well.
Elizabeth hurley..gemini...saving grace was a gemini mike myers, biggest movie was austin powers. youthful, able to laugh at herself, despite amazing beauty
*
Winona rider..sage..jup close to asc. innocent face helped her beat those theft cases. she probably got a way with it all her life with that face, and became addicted i guess.
Justin bieber..scorpio plus scorp asc..plus pluto and north node in scorpio..destined to be sex symbol.(kid was born in 1994, can u believe it?)
Prince harry..capricorn..guardian angel is father, prince charles.cap also rules government.
Jessica biel...in scorpio..i knew it..had to be.
Nikola tesla..aries..pioneering..being by self. guardian angel in his own head, his own self-determination and ideas were his saving grace (He was prolific inventor, google)
Aaliyah..leo..performing, stage presence, creativity, romance.."usher" has same. blessed with performing ability, big stage shows
Demi moore-- pisces...is charitable i believe.
Sorry so sloppy, but it's a good starting point. If anyone knows any particular life/death incident with them, feel free to add on.
Quick note, 5 of these have had issues with cheating partners..namely Demi Moore, Liz Hurley, Sandra Bullock, Jennifer Aniston, JLo. That's usually a sign of Venus in 12th, but with 3 of these, it was Venus ruling 12th.
