A Baha'i who had secret "spiritual marriage" met Abdul Baha in Akka

Phelps (a New York lawyer and religious writer who studied the Bahā'ī Faith and the Radha Soami movement) and Sanghamitta (first woman to convert to Buddhism on American soil) visited `Abdu'l-Bahā in ‘Akkā and stayed with "the Master" for over a month, questioning him extensively. Except for a brief incident wherein Sanghamitta got extremely irritated and vocal with a translator, the visit was cordial and fruitful and resulted in Phelps's biography of `Abdu'l-Bahā (dedicated to M.A. de S. Canavarro).
