When I was pregnant, my husband and I struggled to name our daughter. Ultimately, we both liked Ashby (my grandfather's name). It works for a girl or a boy, and I love that it comes from "ash tree," a symbol of strength. Often, celebs get flack for choosing unusual names, such as Blue Ivy. Reportedly, it comes from Jay-Z's The Blueprint CDs and the Roman numeral for four (IV) -- Beyoncé's and Jay-Z's birthdays and anniversary fall on a 4th. The strong meaning behind their baby's name made me curious about how other stars chose names.
