I am glad to hear form someone who is looking for the Andree name.I having the same problem.
I am basically starting from scratch. I married Richard Andree from the state of Minnesota.
THis past weekend we drove up to Ada, MN to his relatives. We went to the cemetery to gather
information and I got some which helped. Everytime I try to search on the internet or look
in the library I don't have any luck. I almost want to give up. It seems like the name
Andree never existed. The family I am looking for is Christian and Anna Andree. We believe
they may have emigrated from Hanover, Germany. WE know they had a son named Edward and at least 2 daugthters
which we don't have their names. Possibly there are other children as well. Edward married Ellen Rasmussen
and they had 11 children.
This is all we know.

I am not sure if this could be the same family which you are looking for.
Good Luck!
Margaret Richard Andree
