The Life of Ishmael

• Ishmael (son of Abram and Hagar)

• Start — Genesis 16:16. The year of Ishmael (son of Abram and Hagar)'s birth is the year his father, Abram, was born (2010) + the age of his father at Ishmael (son of Abram and Hagar)'s birth (86) = 2096
• End — Genesis 25:17. The year of Ishmael (son of Abram and Hagar)'s death is the year he was born (2096) + his age at death (137) = 2233

Years are anno hominis — counted from Creation as year 1 — which is the frame the source computes in. The arithmetic behind each boundary is given above rather than assumed.
