My question involves name change laws in the State of: Pennsylvania

My husband and I would like to change the last name of my five year old child. I am totally confused on where to start and what to do.

Here are the particulars:

My daughter was born in NYC. We now reside in Pennsylvania.

Her biological father (we were not married) is NOT listed on the birth certificate, however, my daughter has his last name. My husband is NOT her biological father.

Here is the twist: Her biological father was an illegal alien who moved back to his country (Bolivia.) He hasn't had any contact with her since she was 18 months old.

My questions:

#1 - Do I file a name change petition in PA or NY? Is this something I do in civil court or the Supreme Court?

#2 - How am I supposed to notify him? Do I even have to notify him?

# Are there any other difficulties I will have to deal with (outside the norm) to get my daughters name changed, given that her father is not in this country and from a country that is not looked upon favorably by the US government?

Thanks!!
