[MeganFjeld]

Any information or help or leads into the right direction is greatly appreciated.
 
Lars Johansson (Johnson) born Jan 18, 1826 in Eggvena.  married Johana Maria Andersdotter born May 27, 1826 in Algutstorp.  I believe they had the following children prior to their emmigration to the US in 1856.
Britta Stina - b: June 05, 1847
Anders Petter - b: May 15, 1850
Svante - b: May 29, 1855
 
I would truly appreciate any information.  Perhaps their parents and/or brothers and sisters.   Or even the exact date of the departure to the US.  Thank you in advance for your assistance.
