I am a French women researching her Jewish ancestors and cousin. My grand mother's last name was Cavalieri. Her ancestors came from Ferrara and her grandfather had links with this town when he was young. I am trying to trace the Cavalieri lineage and I would like very much to get in touch with anyone who worked on the Cavalieri family, or on the polish Kawaler family from Ferrara. One of my ancestors was named David Cavalieri, as was one of the ancestors of the Kawaler branch of the family. Would someone be able to make me contact Rabbi Foster Kawaler, who worked a lot on the family ?
