There are several Yad Vashem records by Eva ENGEL
Record 1 written in Santiago 30/5/1955 - Eva VAS de ENGEL records the death of her mother Erzsebet MELLINGER daughter of Mor MELLINGER and Terez STERN. This is definetely our EVA - so we can assume she married ? ENGEL
Record 2 written in Santiago 30/5/1955 - Eva VAS de ENGEL records the death of her father Imre VAS son of Samu FRIED and Julia SCHON.
Record 3 written in Israel 10/4/1999 - Eva ENGEL records the death of Ibolyka TREBITS wife of Andor ENGEL
Record 4 written in Israel 12/5/2000 - Eva ENGEL records the death of Josef ENGEL - son of Ibolya TREBITS and Andor ENGEL
Query - Is Eva ENGEL the same person as Eva VAS de ENGEL.
Handwriting on record 1/2 is different from record 3/4 - 45 years has passed so perhaps she had someone else assist her is writing it.
