In the absence of a more specific question about your genealogy and family history, I recommend starting your research at the free FamilySearch.org site.
There you will find a Pakistan Genealogy page which says that it is a:
Guide to Pakistan ancestry, family history and genealogy parish
registers, transcripts, census records, birth records, marriage
records, and death records.
I suspect that your parents and grandparents may have been born less than 100 years ago so if you have trouble finding answers to specific questions about your Pakistani ancestors feel free to ask them here as new questions but pay close attention to our Privacy Policy.
