I have also been able to follow him in that area as Per Simonsson through 1749 at Groeryd, Torpa, Kronoberg. He's not there in 1750 but I'm still working on this family.
My dilemma now is that I'm still trying to find definitive proof that the soldier Per (Simonsson) Groberg is the father of "my" Lars Persson. I believe he is, based on all the circumstantial evidence I have, but want primary source evidence. I've checked for estate inventory records - there is one for his first wife (which I can't read) - but I can't find anything after that. I'm still looking at the tax rolls.
Any idea where else I might look for the proof I need? The birth record in question does not show the mother's name. I've done a lot of research on this family and if I'm wrong, that's ok, I continue to learn a lot.
(If you are interested I will explain why I believe it to be correct.)
