Lars and Magdelone

I would like to know if anyone has information on the married couple Lars - or Laurits (1535-about 1600) - and Magdelone - or Magdeli - (1540-1620) who owned the farm Espeland, in Seim parish, Nordhordland. Of this couple and their descendants, the Bygdebok for Alenfit says: "To this family belonged all the sheriffs of Alenfit from about 1630 to about 1850, and we know that sheriffs in other skipreida also belonged to this family." Of Lars, the bygdebok says: "Farsnamnet er ukjent"...and the same for Magdelone. Several persons displaying family histories in ancestry.com claim this couple are descended from wealthy landowning families in the Voss region of Nordhordland, but to me these connections do not withstand close scrutiny. Any help appreciated.
