I do have a Louise Schroeder in Chicago at the same time but this is a different one and I haven't been able to connect her or her husband to our family. There is another entry Louise Schroder nee Fries.... (I can't be sure of the ending. It might be eshe or eske oe eski) 7 March 1821 to 21 October 1866 from what looks like Viesan, Prussia. Wife of Karl Schroder. No other entries on the copies I have so I don't think I can help further.
