The birth/baptism record for the child born of this couple in 1758 Is a tiny bit clearer. See the link below.   There appears to be mention of the farm called Leusten??  beyond seeing 'besvangret af' (made pregnant by) I cannot decipher the rest.   The bygdeboks for this parish list a small number of farms beginning with L and may be the next best source to turn to.
