Charlotte Warren

Charlotte Warren was a minor witch (or rather witch-practitioner) who was part of a coven in the early colony of Virginia during the 17th century. She later got pregnant by an unknown suitor and gave birth to a very powerful magical baby, Melinda Warren, on October 31, 1670. When Melinda was a child, Charlotte told her about the three powerful witches who helped bring her into the world, the Charmed Ones. During Melinda's youth, Charlotte died, and left the women of her coven to protect her and teach her the ways of magic.

In 3x04 All Halliwell's Eve, Prue, Piper and Phoebe are sent to the past in 1670. They had to free Charlotte from Ruth Cobbs, an Evil witch, who wanted to steal Charlotte's baby, Melinda, and raise her up as her own, evil daughter. After freeing Charlotte, the Charmed Ones wanted to bring her back to her coven when her water broke. The local townspeople were, on Ruth's command, sent to the Charmed Ones and Charlotte to kill them and bring Charlotte's baby back to her. But Prue and Phoebe used the ancient magic they just learned and protected themselves while Piper was helping Charlotte giving birth to Melinda. At the end of the night, Charlotte and baby Melinda are brought to safety.
