'Fram til ca. 1660 bruker Jons enke det ene, mens det andre drives av sønnen Kristen Jonssøn. Han og hustruen Live hadde 10 barn, hvorav iallfall 2 døde små. Kristen hadde visstnok tidligere bodd på underbruket Svebrekke; han døde 1660. Enken Live driver denne halvdel videre til sin død 1674. Hun har muligens hatt sorti medbruker den Knut Steinssøn, fra Gavelstad i Lardal, kanskje svigersønn, som kommer inn på Møyland uti 60-åra. Han ble opphavet til en ytterst dramatisk og tragisk episode, som det har gått sagn om i bygda helt nedover til vår tid. Knut var her som gift mann og fikk i 1663 en datter, som døde året etter; hustruen døde i 1669. Snart etter kom det opp at hans stedatter, Marte Kristensdatter, hadde levd «et ondt levnet» med Knut, hvorved de hadde fått barn sammen. I 1672 ble Marte stilt for retten for «blodskam»; Knut var da rømt sin vei. Marte tilsto «med hendis grædende Taare» at hun jo ikke kunne benekte det hun var tiltalt for. Dommen lød på at hun «for sin grove forseelse» skulle «under Sverdit henrettes och derefter Kroppen paa Baal och Brand forbrendis, och begges eigende Godz løst och fast vere forbrudt». Dommen ble også snart eksekvert — i kirkeboken over døde for 1672 nevnes «den Kvinde paa Møeland som blev halshugget och brent». Kort før var «Møelandstøsens Barn» død; muligens var dette Martes barn.'
translation (with help from Google translate): Until about 1660 Jon's widow farmed one [part of the farm] while the other was run by his son Kristen Jonssøn. He [Kristen] and wife Live [see note below] had 10 children, of whom at least 2 died young. Kristen had reportedly previously lived on the farm Svebrekke; he died in 1660. Kristen's widow Live operated the half farm until her death in 1674. She may have had a relationship with the farmer Knut Steinsen (perhaps her son-in-law), who came to Møyland in the 1660s from Gavelstad in Lardal. He became the author of a dramatic and tragic incident, which has been passed on as legend down to our time. Knut was married and in 1663 had a daughter [Liffur baptized 22 Oct 1663], who died a year later; his wife died in 1669. Soon after came the knowledge that his stepdaughter Marte Kristensdatter was living "an evil manner of life" with Knut, by which means they had a child together. In 1672, Marte was put on trial for incest; Knut deserted her. Marte confessed, "weeping many tears", that she could not deny the charges against her. Her sentence was that for her serious error she should be executed by sword and her body thrown on the fire to burn, and the property of both to be confiscated. The sentence was executed - in the parish register of burials for 1672 is named "den Kvinde paa Møeland som blev halshuget och brent" [the woman from Møyland who was decapitated and burned]. An earlier entry [in the same year] was for "Møland tøsens barn" [Møyland wench's child]; perhaps that was Marte's baby.
Note that Live (Liffur) was not the mother of Christen's children, as he had a wife who died in 1657.
While this source speculates that Knut Steinssøn was Live's son-in-law, it seems more likely that Marte Christensdatter was one of Live's step-daughters (possibly one of the children baptized in 1653) and thus would have become Knut's step-daughter if he married Live. Thus, it seems more likely that Live married Knut after his previous wife died in 1669.
