Abigail was born in 1937 in Transylvania to a family of Hungarian origin. Immigrated to Israel at the age of 10 with her sister, without her parents, on an immigrant ship caught by the British. The two girls were held in a detention camp in Atlit, transferred to Cyprus and when they returned again, they were absorbed in Kibbutz Afikim until their parents joined the family in their home in Kfar Saba. She studied graphic design at the Bezalel Academy of Art and Design in Jerusalem, where she met Yitzhak Yoresh, who later became her husband.
Abigail paints in acrylic colors, usually in small formats using a different technique than usual. The themes of her paintings are portraits of individuals or groups, standing in emptied rooms, or in arid landscapes as if they had gathered and arranged to be forever immortalized in some family album. Some describe it as telling stories in language and visual about creatures, situations and the environment beyond time and space.
