Hi Pam, I looked in the Censuses for information on Madeline but didn't find anything.
I looked in Washington State Archives and didn't find anything for Madeline or Rosiria.
Do you know anything else about them? If not, I'd start looking in Louisiana for Madeline. You could post a message on the Lousiana, Orleans Co (I think that's the county for New Orleans) Message Board. Successful Searching!
