Sorry I seem to be mixed up. In 1910 they were living in New Jersey: Joseph Krause , age 60, born Pennsylvania, wife Mary (much younger); they had daughters, Margaret, Elizabeth and perhaps a Lillie.
In 1900 they were in Philadelphia somewhere: At that time they would have had a son, Samuel with them, perhaps from a first marriage of Joseph.
Joseph born Pennsylvania. Hope this helps.
