Roberta Mae Silvanoff
Born 2 September 1938, Boston, MA, United States. Attended UCLA (she’s listed in a 1956 yearbook), but dropped out before graduating and began singing under the name “Roberta Day” and with her group “Roberta Day and Her Knights”.
Began a solo recording and songwriting career as Roberta Day (or Daye) and continued to release singles thru 1964, but none of her records made it to a Billboard chart.
After marrying in 1965, began using (but did not record under) the name Roberta Phillips.
Re-surfaced in 1966 with the name of “Jonna Gault”. She was now publicized as a 19 year old (suggesting she was born in 1947 instead of 1938).
