Looking for information on the Monamy family of Jersey.

My g-grandmother was Eleanor Mary Monamy (born 1863 St Saviour, Jersey) who married Edwin Isherwood and moved to Pembrokeshire. Her mother was Celestine Monamy nee Benard (born 1826 in France) and her father was John Monamy (born 1824 St Clement, Jersey). Celestine's mother was Marie Benard - variously spelt Bernard and Besnard.

Eleanor had siblings: Celina, Abraham, Lydia, Mary Ann, Jane and Alfred. All born on Jersey.

Any information would be gratefully received. I have the census returns but wonder if I can get back beyond them.
