Taking Back My Maiden Name

The date you change your name back won't have a bearing on your personal power, unless the date has special meaning to you outside the realm of what numerology can calculate.

I'll assume the name you provided with your question is your birth name.

Your heart's desire is the number 9, as is your life path. They support each other.

Your power number, which became active during year 2006, is the number 3, as is both your destiny and your personality. Again, they support each other.

Some things are likely to have changed, though. If you were married before year 2011, your pinnacle cycle number has changed. And, if you were married before year 1993, your life period cycle has changed. You'll probably want to read up on those, as they can make a difference in how you view life and approach its challenges.
