An interesting paper on euro area levels of financial stress arising from household debt (here). Do note that data on which this is based refers to 2008 survey, so is pretty dated by all possible means.
Recall that back in 2008 no one in the Official Ireland was even slightly concerned with household debt levels. I recall AIB senior banking team making rounds through the brokerage houses in late 2008 blabbing out mythological stuff like: "Irish people do not default on mortgages" and "Not a single cent from the State".
Yet, the data in the link above clearly shows that Ireland was already building up some serious payments problems:

But the really interesting chart is the following one:
