I would not have believed these were our subjects, but the Swissvale enumerator did exactly the same thing with Emma's brother, William C. STRAUB; that is, the enumerator made William and his wife a young couple with no children.  What did this enumerator do, walk around reading the mailbox labels, then guess at the rest?

The question here is whether John is the biological nephew or Emma the biological niece, but the fact that Emma (__?__) SIMMONS continues to live with Emma (STRAUB) ANGER after the younger Emma's divorce suggests that the blood tie is between the two Emma's.
