Dear Madhusmita,

Sorry for late reply, hopefully you have solved the issue but if you not then here are is my advice... first of all there is lot more than you have mentioned here.

First and foremost, he came to see your elder sister, what happened then, did he denied or your parents denied ?
Secondly, How you both came into touch ?

Because , even though he is 10 years older than you but there must be other reasons too that your family is denying him. You have to work on those then only things can move ahead.
