I want to get her marry.. how can I approach my parents please give me advice..

Remember you're the one who is going to get married not them.Take the same approach your sisters did,it might be hard but in the long run you'll be much happier

Explain to them how much you love this girl and want to spend the rest of your life with her.

Why were they upset/angry about your sisters getting married?
Religious beliefs or something else?

What country are you in?
What country are you from?

You can't live your life according to your parents expectations unless you are willing to be miserable knowing what you might have had.
Does this girl love you back?
I wouldn't make an issue of it until you have an idea between you and your girl. Why open a can of worms with others until you know the situation and where it is going.
