Naro and Zita Lockford

     I came across a blog (here) that described an act that surely made contact with Nattova and her world of performers. According to that blog,

Naro and Zita Lockford were a French brother-sister adagio act who came over to the U.S. in the early 20s from the Folies Bergere. In 1922 the two appeared in the Broadway show The Rose of Stamboul, and for at least the next four years they were a big time vaudeville staple. In 1928, Naro was telling the papers that Zita has retired and returned to France. He soldiered on with larger, more elaborate acts, at least until midway through the 1930s.

     Nattova, too, considered herself French and performed at the Folies Bergere. She, too, specialized in what came to be called an "adagio" act. It appears that this duo came to the U.S. about three years before Nattova.
