The One Person Missing from the List below

My Oldest Sister Lis. I didn't include her because I never got to know her well enough to know how much she loved me. Nor how much I loved her. I admired her enormously as she was extremely intelligent with a personality to match. As can be seen in her eyes. There was an 8 year difference between us. She didn't immigrate with us as she was in College. After Graduation with a Degree in Physiotherapy she married one of her patients and moved to Finland at age 21. She had two daughters and I saw her once in 1960 when she came for a brief visit. Tragically and unexpectedly, she died of Acute Leukemia at the age of 27 in 1963.
