Judy Hill was born Annette Verheyen who was born in Den Bosch, in Den Bosch, Noord-Brabant, Netherlands The Netherlands. She was a singer who recorded under the aliases of Annet de Kok, Annet Decock, Judy Hill and Judy Hil. Since her first records were in the mid-60s I would guess she was born in the mid to late 1940s.
The first record release I can find for her was in 1964 with a 45 r.p.m. release of Lagune Am Blumensee / Eine Wilde Rose on the Fontana label. In 1970 she began recording under the Annet De Kok alias and in 1976 she was recording as Judy Hill.
I can find no biographical information on her other than what I have presented.
