Pehr Lundström, Umeå

[alice]

Hello,
I am searching for information on my great greatgrandfather.  Pehr Lundström was born in Umeå, Norrland on December 9, 1818.  I do not know who his parents were but I do know that he married Maria Andersdotter from Björklinge.  They had 2 sons that Pehr put in Allmänna Barnhuset in Stockholm after Maria died in 1848. I would like to know who were Pehr's parents or if he had any brothers or sisters.
Thank you in advance for your help.
