Name Change

i HAVE TWO CHILDREN ONE IS 19 MONTHS AND THE OTHER IS 3 MONTHS THE FATHER IS NOT ON THE BIRTH CERTIFICATE AND HAS LEFT THE COUNTRY SINCE HE IS WAS NOT HERE LEGALLY...IS THERE A WAY FOR ME TO CHANGE BOTH MY KIDS NAMES TO MY LAST NAME AND WHAT IS THE PROCESS FOR THIS.

I'm getting married and would like to know if it is legal in Illinois to have two last names without hypenation. Also, may I use the last names interchangably? Besides financial items when do I NEED to use my full legal name?

I got married in puerto rico and reside in new york. I have the marriage license from puerto rico. I would like to change my last name to my husbands name. What do I need to do?

I was born with the last name Piccola. However, a few years after my mother remarried, she had my name on my social security card changed to Osgood (My step-fathers name; I am currently 22 years old). This is the name I have used since that point (It is also the name on my drivers license ) However, my birth certificate still says Piccola. I am trying to apply for a US passport, however, I am told that I need to provide legal documentation of my name change (my social security card and drivers license will not suffice) Unfortunately, I have no such documentation, all I have is my changed SS card and drivers license. Could you please tell me what to do about this/how to fix this/direct me to the correct forms? Thank you.

Can I change my name to my married name on my license, passport, with creditors and such if I do not change my social security card? I want to use my maiden name for work and the only way I can do that per my job is if my social security card does not change. I want to be known for all other nonwork purposes by my husbands name. The marriage license has my maiden name and husbands name listed as last name with no hyphen.
