Do you have any more information regarding Joseph J Andert and Anna Unger?

I am looking for information about Joseph Andert whos fathers name was also Joseph Andert, but I do not know mother or wife of either Joseph Andert.

Joseph Sr came to the US @ 1907 and was a carpenter
Son Joseph came to the US @ 1909 and was a baker
According to the 1910 census they lived in Ward 12 in Manhattan.

It does say that they were both Jewish and from Russia, but ???. I do know that Joseph Jr was Jewish.

Thank You
