Annie Cox born 25 June 1872 Aghadowey district was the daughter of William Thomas Cox, labourer, Lisnamuck, and Isabella Nelson, Bovagh. They were married 9 Mar.1863 Coleraine Registry Ofice and had several other children. Daughters Isabella (age 6 in Dec.1871) & Matilda (age 5 in June 1873) both attended Milltown Female School in Aghadowey but no sign there of Annie, so perhaps she died young. The family were Presbyterian and have a plot in the church at Aghadowey but there is no gravestone.
Just because people have the same surname does not mean that they are related to each other.
