Melle Whitehead was the sister of Alice Whitehead and who, like Brooke Davis, apparently had problems getting pregnant and eventually found out that she couldn't.
Alex stated that her sister was a lot older than herself, which may have been the reason for her fertility problems, although Brooke doesn't believe she existed. ("You Know I Love You, Don't You")
- Despite her problems, Brooke eventually fell pregnant and gave birth to twin sons. It's unknown if Alex's sister, like Brooke, fell pregnant or had a medical assistance and finally had children.
- If she finally had children, Alex would be an aunt.
