Amy Yancey was a pre-War American citizen who was accepted into Vault 114.
Living before the Great War, Amy, her husband Murry, and their sons Jimmy and Ronnie were all designated to live in Vault 114. Their family, the Yanceys, were assigned to the Residency A2 section of the vault. However with Vault 114's unending construction they may not have been there when the bombs hit Boston.
Amy Yancey is mentioned only in Fallout 4.
