A Slovak-Hungarian priest. Ferenc Dénes was known in the United States as Francis C. Denes. By the mid-1890s, he was already serving in New York as pastor of St. Elizabeth of Hungary Roman Catholic Church, where he strove to minister to the ethnically diverse congregation amid tensions between Hungarian and Slovak parishioners. In 1897, following the Lattimer Mine massacre, he traveled to Hazleton to assess the situation of the Hungarian strikers and explore ways to assist them. In 1905, he also played a role in the organization of the Hungarian Catholic community in New York; the first meeting of the Hungarian Catholic Club was held in his apartment, located within the church building. From 1905 to 1907, he served in the Roman Catholic community of Heilwood, PA. He later worked in Akron and then in Barberton. Due to a serious illness (insomnia), he returned home and settled in Érkeserű. The date of his death is unknown.
