John Daly

I only have a death certificate for my great-grandfather, John Daly, who died in NYC in 1896 when he was 38 years old. It stated that he was 38 years old (about 1858) and his parent's names were Owen Daly and Rose Devlin. So far I have found a brother, Peter Daly (born est. 1860) and two sisters, Bridget (born est. 1862) and Alice (born est. 1868). They all came to New York City in the 1880's. All of the records I have found here gives their age at the time but no exact date of birth. If I have multiple records for them, they give different ages/date of birth for each one so I cannot be too precise on when they were born. The two sisters said that they were born in Tyronne County. My Ancestry DNA lists my Irish ethnicity estimate as Tyronne County and even narrows it to South Sperrin Mountain with Greencastle & Plumbridge. I did find an Irish birth record for Arthur Daly, born in 1869, parents Owen Daly & Rose Devlin, in Binnafreaghan, Gortin.  Also, in a 1901 Irish Census, with an address of 21 Binnafreaghan, Fallogh, Tyronne, it listed father- Owen Daly (born 1831) mother - Rose (born 1837), son - Arthur (born 1877), and daughter, Mary (born 1871). I am trying to find out where the Daly family lived and all of the family members.  Thanks so much!
