How many women were with Imam Hussain? (At the battle of Karbala)

As possibly many of you know, at the time of Imam Hussain (a.s.) there was a tragedy event which was and is famous as Battle-of-Karbala. For more info. you can read the following link: www.al-islam.org/the-tragedy-of-karbala I was wondering regarding its women numbers. In other word, I wonder how many women were with Imam Hussain at the event of Battle-of-Karbala? Is there any statistics concerning that? **Note:** As much as possible, I’m looking for the Shia view (references). Although Sunni’s views would be appreciated as well.
