Short answers, pulled from the story.
Gerlög and Inga were two powerful women who lived as a mother and daughter in 11th-century Uppland, Sweden. Their family saga appears on several runestones to document their rights of property over the estate Snottsta.
Gerlög and Inga lived during turbulent times of religious wars between Pagans and Christians within the context of 11th-century Sweden. These conflicts concerned sacrifices at the Temple at Uppsala while both women chose the new faith.
Inga inherited the estate Snottsta from her son according to the inscription after both Ragnfast and their unnamed son died without leaving direct heirs. This legal outcome is rare for the time period and four separate stones at Snottsta and Vreta confirm this inheritance chain.
Their saga has been the center of an exposition at the Stockholm County Museum where the museum dramatizes their story for contemporary audiences. A page titled Inga och Estrid - en såpa för tusen år sedan exists there alongside another exhibit called Gerlögs berättelse - fakta och fiktion.
The runemaster of U 329 was a man named Fot who created multiple stones connecting the families while the transition from Paganism to Christianity happened. His work connects the Snottsa and Jarlabanke families visually and textually through shared ancestry with Estrid and Gyrid.
