My granddad's sister was Annie Cushley or Costello - born in Bellaghy in 1884 and married a McShane in 1904. Annie appears in the 1911 Irish census as living with or visiting her parents in Bellaghy. Also present is her son Manus born 1907 but no husband (possibly working somewhere else?).The census says she was still married and had been for 7 years and that she had had 4 children only 1 of which was alive at that date.
If anyone has any information on what happened to this family I would love to hear from you.
