Plant ID, please?

These pretty little white flowers are popping up in lawns and flower beds just about everywhere I go at this time of year. Can someone tell me what they are?
The individual blossoms are, on average, about the size of a US quarter/twenty-five cent piece, or slightly larger.

Many thanks!
