My Godmother and 2nd cousin Dorothy Aloi (Prev. McDevitt) who just passed away last week is a first cousin to Donald. Helen is my great aunt, but I just learned about her in the last hour, and did a search. She was my grandmother's sister, I don't know what happened to her, no one ever mentioned her. She was sisters to Lily McDevitt, Alice McDevitt, and Edna Hazard. Dorothy was Lily's daughter. Edna was my maternal grandmother. Alice was a nun. Donald and his son Pat were in attendance at Dorothy's Funeral.
So I guess, Leslie Randall would be my great uncle by marriage.
