Actually I've spent hours digging ever since the first question was opened. I found them in Norfolk, VA in the 1910 census. There they state that Pauline was born in Virginia and they had been married 9 years (since about 1901). I didn't find a marriage record in Virginia. I've looked at every Rosenstein I could find. I did find one interesting family but the dates don't quite jibe.

Samuel b May 1876
Ida b July 1878
Dinah b Feb 1881
William b Nov 1882

Meyer was the son of Samuel Rosenstein d 1936 and Pauline Majerczyk. Since your Ida named her daughter Pauline, I thought it was at the least an interesting coincidence. Meyer Rosenstein is buried at Bayside Cemetery in Queens.
Don't be turned off by them saying "Poland." In another place it says Germany.
