Henry's second wife and Abe's adopted mother. Henry met her toward the end of World War II when they were working as medical personnel near one of the Nazi concentration camps. Over the years, she worked as a nurse in addition to being a housewife. The latest time period in which Abigail has been shown is 1982, when she was still married to Henry but looked a generation older than him (Janet Zarish); in 1984, she vanished without a trace despite Henry's best efforts to find her. Henry has acknowledged that the end of his relationship with Abigail caused him a lot of pain that prevents him from dating anyone for whom he has real feelings. In the episode "The Night in Question", Henry learns from Adam that Abigail killed herself after a car crash to prevent Adam from finding Henry. Abigail appears in ten episodes.
