jain, who is telling you this silly nonsense? That is absolutely absurd. Someone is having a good laugh at your expense. Do not listen to them. They are being very rude to you both.
If you cannot find any close relatives that you both have in common, you are
not related. I know so many people with the last name of Singh. I am sure you do too. Are they all closely related? No.
If you eventually find some relatives somewhere in your family history that are related, you will find that the relation is so distant, it won't make any difference. You are not brother and sister. You are not first or even second, cousins. So, go and feel free to court this girl. Be happy. May you both fall in love and someday be married with all the blessings of your families backing you.
