O Reilly T Ryelly Bridget

I am hoping to trace Bridget T'Ryelly (O'Reilly) who came to New Zealand on the FernGlen in 1879. Note there were approx 53 passengers on this ship unnamed and she was one of them. Bridget would have been about 20 years of age at the time and travelled with her two sisters, Ellen and Catherine. She was born in Tipperary Ireland.
