Guessing the Ascendant

[siamese_dream]

This post is about Michelle Williams, an actress most famous for her starring role on the TV show Dawson's Creek. She is also the ex-fiancee of Heath Ledger and the mother of his child. Astrotheme does not have her birthtime, so I was wondering if anybody could try to figure out her rising sign. Her Sun and Moon are both in Virgo. I have attached a picture of her.

Some important info that could help form her chart (from wiki)...
Growing up, her mother was a homemaker and her father was a well-known stock and commodities trader.

She was born in Montana, but moved to Cali at age 9.

She emancipated herself from her parents at age 15 because they disapproved of her acting.

She left school after the 9th grade to pursue acting.

In 1997, she won the Robbins World Cup Trading Championship, as her father had done 10 years earlier. She won after turning $10,000 into $110,000 over the course of a year and that gain (as of 2006) is the fourth highest in the history of that competition (her father has the highest).

Thanks in advance to anyone who can help!
