I am trying to locate any information on Helen Zack. I believe she lived in Portland but am not certain. She provided the information for the death certificate of my "missing/now located" aunt, Nellie McFarland Reimers and I am hoping to learn more about this unknown ancestor. Does anyone have any information to help me locate Helen Zack or her children? My aunt's last address was 2480 N.W. Quimby Street if that will help. Many thanks. Conni in Ohio
