Thank you for the response! Yes Mary had siblings. I am not confident yet in the names I have acquired from my sister in law. She knows there are more but could only think of these: Kate, Eleanor and Stella. She wasn't sure if they are sisters or sister inlaws!

I have a copy of Mary Ostrowski's immigration papers, also a newsclipping from Walter and Mary (Ostrowski) Frahm's 50th wedding anniversary, a copy of their marriage license.

In the 1910 Census used for her immigration purposes she is listed............

Frahm, John Head - no age listed - Place of birth Germany-citizenship Naturalized.(year of immigration 1873)
----Anna, Wife
----Walter, Son
----Theodore, Head
----Ernestine, Wife
----George, Son

Address was listed as 180 Waterman Ave, Detroit, Wayne County, Michigan.

We do not know who Theodore, Ernestine and George Frahm are.
