Names like:Grace, Eve, Faith, Delilah, Genesis or Mary What it says about you: A biblical baby name doesn't guarantee that a family is super religious or practices a certain faith -- but it's a good bet! Nameberry's Linda Rosenkrantz says devout families of all faiths -- Christian, Jewish and especially Muslim -- will invariably opt for a spiritual choice. "Faith is the most vital element they wish to impart to their child," she says, "whether it’s a straightforward Puritan virtue name such as Faith, Grace or Mercy, or Destiny, Genesis and Trinity, which came into favor in the '90s." (She adds that rappers have made "some extreme choices" in the religious names category, "like DMX's Praise Mary, and L'il Mo's daughter God'iss Love.")
And while many parents pick religious names based on their biblical associations, that's often not the only reason, says Wattenberg. Many secular families are also attracted to their trendy sound (for example, Delilah, or Noah), while New Testament classics like John and Mary reveal a parent's stylistic conservatism.
