Anders Pehrson b. 1839, to Aalborg, Denmark in 1860s

[Georg Petersen]

I am searching for the birthplace and ancestors of my great grandfather Anders Pehrson (Persson, Pedersen, Petterson) born c. 1839 somewhere in Sweden. He moved to Aalborg before 1868 to work at Kj?rsm?lle Kl?defabrik og Uldspinderi, a company that employed many Swedes. He married Christine Amalie Christensdatter in Aalborg 31.1.1869. They got 7 children, among them my grandfather Edvard Emil Georg Petersen b. 1876 who later moved to Oslo, Norway as a carpenter. Does anyone know where he could come from? Migrant workers are often recruited from the same area. Are there any registers in Sweden I could check? None of the Danish registers lists his birthplace.
