My mother Rosemary (Rosemarie) Blackmon was born and raised in Lackawanna/Buffalo area. She was born 4-13-37. Her parents were Howard and Anne Blackmon. Brother Edward born 1930. She had 2 sisters Margaret Anne (Ann) who was born 1920's, and Elizabeth born a few years after my mother (37). Both girls were mentally challenged. Margaret Ann was committed to the system before 1934. I have a picture of her sitting outside of the administration building at the, New York State School in Newark, dated 1933/34. Elizabeth born around 1940 was committed before she was 5, to the same institution as her sister. My mother is now 80 and desperately wants to know what happened to them, she is the only living sibling as my uncle passed 1n 1998. She does not know if they are alive or deceased. We assume deceased for Margaret due to her age, assume the same, but unsure about Elizabeth. If they are deceased we are seeking their burial site. My mother is just seeking closure to this painful situation for her.
