My children rush every morning (even on a school day) to open their advent calendars. Okay, I admit, it's the chocolate they're after. When I was a child, there were just pictures of Christmas related items like holly or an angel (how old do I sound?). Still, it was an exciting little offering each day in the countdown to the special day.
Ancestry.co.uk have put together an advent calendar of geneaology related hints, facts and other offerings. Even though it's now the fourth day of December, you can still open windows one, two and three.
Have a look.
