Thank you for posting. My 2 lost girls are from other Jankowiak families and were both born in Poland.
However, the 2 you have researched are:
Marianna,b.1885 in Bay City, the daughter of Phillip Jankowiak and his first wife, Kate Ratajczak, married John Stachowski in Bay City in 1908. Her sister,Veronica aka Cora, married John Kowalski in the same year.
Maggie, b. 1893 in Bay City, (Magdalene or Margaret, daughter of Phillip and his second wife, Marcianna Swiecicki), married Louis King in 1918.
Victoria Wichlasz Jankowiak (1847-1920) is on the 1910 and 1920 with her second husband, John Stefaniak.
Thank you for your efforts.
PS Here is the link to the Maggie I am seeking on the 1880 census. I have the records on her sister, Mary F ( 1873-1938):http://search.ancestry.com/cgi-bin/sse.dll?db=1880usfedcen&a...
