Each January in the four decades since the Roe v. Wade decision legalized abortion in 1973, Nellie Gray marshaled tens of thousands of anti-abortion demonstrators for the March for Life rally.

Now, after Gray’s death in August at age 88, a woman less than half her age will take up the cause to lead marchers from the National Mall to the Supreme Court on Jan. 25 to protest the 40th anniversary of Roe v. Wade.
