Journey to His Past

Where in the World is Timothy F. Corcoran?

One of the first records I look for when researching an ancestor is the census record.  I try to follow my subject through the years in the census.  Nothing frustrates me more than when I cannot locate the ancestor in the census record.  I know he/she did not fall off the face of the earth, so where are they hiding?  In the case of Timothy Corcoran, I can't find him in two censuses. 

Timothy would be four years old in 1880, but I cannot find his family, who I believe is father, Timothy; sisters, Hannah and Josie; brothers, John, James, and Patrick.  Timothy was born in Chicago, Illinois and I thought they would be living in Illinois during this time.  Timothy was 23 in the 1900 Census.  The census that year was taken in June.  Timothy married Helen Smith (Schmitt) on 5 June 1900 in Pullman, Cook, Illinois.  Did this contribute to my not finding him?  I have been known to go through the census, page by page, but I am not ready to attempt that for Chicago!

The table below shows where in the world Timothy Corcoran was?  If you have any information on this family, please leave a note.  I am going to find Timothy in the other census dates.
