Dr. C. C. Parry's first wife was Sarah M. Dalzell. His second wife, who survived him, was Mrs. Emily Richmond Preston. His mother and his only daughter were both named Eliza. His second wife's daughter from her first marriage was named Harriet. None of his sisters or half-sisters was named Eva, and as far as I can determine none of his brothers ever married an Eva; so who was Eva?
