Relatives of the Mailich relatives I just found out about?

My brother was recently in Washington & went to the Holocust Museum. He found a document in which my mother Ruth Kornblum ne Mailich had tried to find relatives after the war. Greta Opet ne Mailich, Marta Dietrich ne Mailich, Sally Mailich, Betty ( Berta) Mailich ne Glass, Max Mailich, & Rosa Mailich ne Metz. Growing up my brother & I had no relatives on my mother's side of the family. My mother's father was Gerson Mailich. born in Tremsin Poland. ( 1887) We knew nothing of these family members.
