I am looking for two sons of Andrew Otto Engel b. 1894 in Huntington, IN.Their names are William and John. Their Mother's name was Patricia.Their half sister is my Mother, Joan Patricia Engel Clark, of Indiana, who lost track of her brothers many years ago.William and John would have been born sometime between 1925 and 1940??They were raised in or near Racine, Wisconsin. I would really appreciate any help in locating them.
