R' Eliazer of Dubna had two conflicting years of death, 1641 and 1793, and neither makes any sense. His daughter Chaya was born 1695 (54 years after father's death?) and died 1740 (53 years before her father died?). Also, his father Rabbi Isaachar Berish was born 1630 (11 years before the death of his son?!) and died 1690 (102 years before his son?).
