The 1930 US Census lists Frank and Anna living at 1008 Buffum Street, which is near their previous location of 900 Fratney St. This would be the final place that Frank and Anna live. Their son, Frank Jr., still lives with them. Frank is now retired, having done that sometime between 1920 and 1930. Their daughter, Agnes and her family live at the same location.
Interesting to note, it lists both Frank and Anna as being born in Germany. Though, this can get confusing as that area of Europe went through a lot of changes. It’s been listed as Germany, Poland, German Poland, etc. They did leave from Bremen, Germany, but that was one of he major ports of departure.
