Where an unmarried mother has registered her child without the natural father and now wishes to add him to the child’s birth entry, a re-registration can be arranged by appointment.
Os yw mam ddibriod wedi cofrestru ei phlentyn heb y tad naturiol ac nawr yn dymuno ei ychwanegu at gofnod geni'r plentyn, gellir trefnu ailgofrestru drwy apwyntiad.
