The 1911 Irish census. Shown below is the segment for my 2nd great-grandfather Thomas Crehan's house in the village of Creeveroe (Davies), county, Galway. As with the 1901 census he is still living at house number 8. However, the ages on the 1911 census do not match up with that of 1901, but this is not unusual for records of this time period.
