How many women attended Vatican II?

At Vatican II, which took place from 1962 to 1965, there were no female voting members among the bishops and cardinals. However, women were present as auditors, consultants, and staff, with estimates suggesting around 30 to 50 women attended in various capacities. Notably, figures like Sister Mary Luke Tobin and others contributed to discussions, although their roles were not equivalent to those of the male participants.
