(April 23, 1940 – December 2, 1980) was an American Maryknoll Sister who served as a missionary in Bolivia, Chile and El Salvador.

On December 2, 1980, she was beaten, raped, and murdered along with three fellow missionaries — Dorothy Kazel, Maura Clarke and Jean Donovan — by members of the military of El Salvador.

[1][3] Following in her relative the Bishop's footsteps, Ford had confided in a high school friend at the age of fifteen that she not only wanted to be a nun, she specifically felt called to be a Maryknoll missionary sister.

After spending a required "reflection year" in the United States, 1978–1979, before taking permanent religious vows in March 1980, Ford moved with Piette from Chile to El Salvador, arriving the day of Óscar Romero's funeral.

In this mission, Ford worked with the poor and war victims, providing food, shelter, transportation and burial.

Altogether, Piette and Ford had worked together in Chile and El Salvador for seven years, until their deaths barely three months apart on December 2, 1980.
