I was looking at the census records for Lars and found him and Kirsten. You had said that Lars had been married before to Anna Margrethe Madsdatter and they had a daughter, Kirsten (b. 1781), who shows up in the 1787 census. It also shows another child, Else. Google translation translated both as "daughter of this marriage". So is google wrong and is both Kirsten and Else daughters of Anna, not Kirsten?
Just out of curiosity, how do you know so much about these families?
Thanks for all your help. I hope I'm not pestering you with my questions!
