2 questions about research while traveling to Israel

Elise Miller <elisefmiller@...>

Is there a central source for finding the gravesites of ancestors who I know are buried in Israel?

Can I do research about the fate of family members who were in Romania and Hungary during the Holocaust at Yad Vashem or elsewhere in Israel?
Thanks you for any information about these queries.

Thank you for your help!
