I-130 family name question

[r8edx2000 2]

Well hello VJERS im new here so thanks for reading my post. Im about to start my ir-1/cr-1 jorney soon. i have 2 questions, my wife-to-be is from mexico and uses two last names do i need to put both last names as her family name or as her maiden name or do i just use her first last name. second her name is MARIA DEL ROSARIO does this count as just her first name or does this mean she has a middle name? how would i break it up to input it on the forms if considered a middle name. thanks in advance.

My wife's name is Emma Rosa (that is her first name), no middle name, and then Sanchez Flores.

We put Emma Rosa as first name, nothing for middle name, and Sanchez Flores for last name and had no problems any place in the process.
