Euphrasie Josephine Eugenie Euphrasie “Flossie” Monpeurt
Here are either versions of her maiden name, from transcriptions of her children's records:
Flossie Mophet Momfert Momperb Moffat
Here is her husband https://www.wikitree.com/wiki/Speicher-1058
(I am attaching their children, at least one of whom is unconnected from the main tree). The husband is German, from the Saarland, he is a distant relation of mine.
I could create her now, but I am not sure of the maiden name, so hesitate...
