Olof Eriksson & Johanna Hansdotter

[Shawn Bagnall]

I have been having some trouble finding this line.  I found my GGGG Grandparents Olof Eriksson and Johanna Hansdotter with their children in 1799-1806 Håby, Göteborg och Bohus; HH Examination 908.7.81000.  It appears they leave in 1800 and 2 of the children return (HH Examination 908.8.88000).  The boys Erik and Johannes are noted as being beggers.  Johannes is my GGG grandfather.  I would like to be able to follow his parents information back further.  Can anyone help me find out what happened to them and where they were from?  Also what happened to the other brother Hans?  Both Eric and Johannes named their firstborn sons after him.  
I believe I have found the marriage record for Olof Eriksson and Johanna Hansdotter in Håby GID 908.11.1300.
Any help would be truely appreciated.  
Thank you  
Shawn
