His wife, Sesselja Thorsteinsdottir was daughter to Thorsteinn Olafsson and Setselia Davidsdottir. His siblings were Helga, Thorsteinn and Grimur.
Hallgrimur "the strong" Thorsteinsson was born in 1794 in Brattingstad un Flateyjardal, was a farmer at Vík in Flateyjardalur and had a sibling Gudrun Thorsteinnsdottir (1806). His parents were Thorsteinn Grimsson and Gudrun Sigurdardottir.
Thorsteinn Grimsson was born in 1773, married Gudrun in 1793 in Thonglabakki, Sudurthingyjarsysla, Iceland. Gudrun was born in 1765. He was a farmer at Brettingsstaðir in Flateyjardalur. Thorsteinn died in 1842. His father was Grimur Hallgrimson.
Grimur Hallgrimson was born in 1744 and died in 1819 and was a farmer at Brettingsstaðir. Credited with saving many people from starvation during the eruptions of 1783-1785. Móðuharðindin (English: The Mist Hardships) was a natural disaster which took place in Iceland in the years 1783–1785, following the volcanic eruption of Mount Laki. The hardship began with the eruption of the volcano in Lakagígar on June 8, 1783, which was one of the greatest volcanic eruptions in historical times. The eruption devastated Iceland and the environmental effects could be felt in many places throughout the world, due to the severe global meteorological effects of the rising sulphuric fumes. Jón Steingrímsson, a local Lutheran pastor, grew famous because of his eldmessa ("Sermon of Fire"), which he delivered as his congregation took refuge in the town church. His sermon was credited with stopping the advance of the lava flow. It was later printed as Eldrit in 1788. After the volcano erupted, it emitted a lava flow which lasted for about five months. Additionally, and even more devastating, there was a poisonous mist of fluorine and sulfur dioxide which settled over the entire country, burning up grazing lands and killing livestock, and lasted far longer. It is believed that up to 80 percent of livestock died, and an estimated one-fifth of the human population of Iceland (approximately 10,000 people) perished from the combined effects of the mists and the ensuing famine caused by their loss. It is estimated that 14 cubic kilometers of molten lava flowed from the volcano, making the eruption the world's largest recorded lava flow.
