According to TCP (Desmond), James repudiated his first marriage, and declared his issue by that marriage to be illegitimate, on the grounds of consanguinity, Joan being shown as daughter of Maurice Roche, 6th Lord, Eleanor, daughter of James's younger brother Maurice. TCP specifically reports that this made her his grand-niece. BE1883 (FitzGerald of Desmond) disagrees and identifies her as daughter of 'Maurice the Mad' 4th Lord Fermoy, with consanguinity also being the reason for the repudiation (as a cousin). The dates make that seem much more likely so we follow BE1883 as to her identity. Whatever his relationship with his first wife, the repudiation of the marriage not only upset the Roche family but also led to disputes between his descendants as to who was the 'real' Earl.
