I am a single parent who has being raising for the past 10 years . I am looking for grants, sponsorships or scholarships. My daughter is going to start HS in Sept in a Paroquial school. I find websites only for grants for College.Please help

You should ask the school if they have any available scholarships, because private schools like that usually do.
I also found these websites for you that may be of more help:
Children's Scholarship Fund (http://www.scholarshipfund.org/index.asp)
Affording A Private School (http://privateschool.about.com/od/financing/Affording_a_Private_School.htm)
Scholarships (http://privateschool.about.com/od/scholarships/Scholarships.htm)
How to get financial assistance for private school tuition | BabyCenter (http://www.babycenter.com/0_how-to-get-financial-assistance-for-private-school-tuition_64647.bc)

I think the first is only k-8 but the otherones have other links inside the articles.

Good luck!

Thank you I will look into this websites. I appreciate it . :)

The website gives me info on outside cities I am from NYC

In that case try these: The Children's Scholarship Fund, New York City (http://www.scholarshipfund.org/nyc/howtoapply.html)
Scholarships (http://www.stgregorymanhattan.org/scholarships.htm)
School Choice of New York - Scholarships - Laws (http://www.nyschoolchoice.com/scholarships/)
FinAid | Other Types of Aid | Scholarships for Private K-12 Schools (http://www.finaid.org/otheraid/privateschoolscholarships.phtml)

Hope these help more, there speciffically New york schools except for the last one which is a list of scholarships for all states, but includes NY
