Yizkor (a special prayer for the deceased member) is recited in synagogue. If your husband had a brother or sister I would confer with them. If your unable to communicate with his other Jewish family members, you may still visit the cemetery, provide a prayer of your own faith, and leave a small stone, perferebly though at your husband's request on the anniversary of his death.
