To celebrate its database passing its 8billion records milestone earlier this month, My Heritage is opening up its collection of one billion census records for seven days.
While Irish family historians are accustomed to having year-round free access to Ireland's 1901 and 1911 censuses, it's not often there's a chance to delve into the US (1790-1940), Canadian (1825-1911) and England/Wales (1841-1911) collections without charge.
Extracts from the Scotland 1841, 1851, and 1861 censuses are also included, as are censuses from Denmark, Sweden and Finland.
You don't need to register or provide any personal details to get access. Just go to MyHeritage's Census search page and get started.
