familysearch.org lists a Jehudith Resnick born 1944, deceased. (They don't display entries for living people.) If you create an entry for yourself and your parents/grandparents, if a couple of days their computer may connect you up to vast hordes of ancestors which might include your singer.

Another site, ancestry.com lists a couple of candidates, one of them was in HS in 1962 in Hartford.
