Emily Josephine Heaviside was born in Dublin, Ireland in November of 1839. Her parents were John Burrows Heaviside and Alice Staunton. John and Alice had seven children. In addition to Emily, there were three brothers who would also emigrate to New York, William, John and Henry; one brother remained in Dublin, Charles Albert Heaviside, he married and later one of his sons would emigrate to Brooklyn, New York; and two sisters – Catherine Matilda who married Henry Duncan Thompson and they emigrated to Australia; Alicia Henrietta Heaviside, born in 1842. John Burrows Heaviside was the son of a man bearing the same name who was married to Catherine Witherington. Catherine’s sister Martha, was married to the Irish revolutionary Theobald Wolfe Tone. Emily Josephine’s brother Henry would name his son John Burrows Heaviside. This name is carried on to this day by John B. (Jack) Heaviside of Long Island, New York, whose extensive research into the Heaviside family in Dublin, New York and his connection to descendants in Australia have provided a wealth of information.
Emily married Simon Dunn (sometimes Dunne) in May 9, 1863 in Dublin. The following year the couple emigrated to the United States aboard the Steamship City of Limerick out of Liverpool, arriving in New York on July 11, 1864. Simon’s occupation is listed as “broker” on the ship’s manifest. Simon’s father is listed as Christopher Dunne on his marriage certificate. Nothing else is known of Simon’s ancestors or siblings.

He is listed in every subsequent directory until 1880, when he has moved to 110 Cherry Street. He is at that address until 1884, when he is listed at 104 Cherry Street.
