Actually I think I've found his origins, but there are some inconsistencies and I have a gap between when the Lars that's connected to his parents in Möklinta vanishes after 1784 and the Lars that's connected to his wife in By appears in 1791. There are no moving records in either parish that cover that time period. On top of that, the later Lars first appears with a birth year of 1757 instead of 1754, though that gets changed to 1754 after a few moves. Finally, Lars' birth record says his mother was Anna Olsdotter, but his death record says it was Anna Ersdotter.
I think Ersdotter was probably an error, but I really want to close that 7 year gap to be sure it's all the same person.
I flipped through every page of the Möklinta HHE book for 1785-1794 and did not find him, so I think he may have moved to By in 1784. Before I search every page of the By 1786-1795 HHE books (443 pages in 2 volumes!) does anyone know if ArkivDigital indexes go back that far? If so could someone with a subscription do a search for me?
I've written up everything that I've found in his profile, between the biography and the research notes.
Tusen tack!
