You will have to discover where in Poland your grandmother was from, when she was born, when she came to the U.S., etc. If she was naturalized (became a citizen), that would be a good place to start. Her death certificate, or the birth certificates of her children, might also have the information.

If she came to Ellis Island, you can check Ellis Island records on-line - her approx. date of birth and (perhaps) former residence in Poland might be listed.

It's a common, but very wrong, belief that everything you need is on the internet. While the amount of data is vast, it's very rarely just handed to you on a silver platter.
