Many sincere thanks for the information about Edmund Kennedy and Mary Hurley. The existence of son, John, was unknown to me.
The real quarry for me are two other presumptive children of Edmund Kenndy and Mary Hurley:
1. Arthur Kennedy, b. ca. 1810 Ireland, d. 1896 Queens, NY, married to Catherine Griffiths, b. ca. 1820 Ireland, d. ca. 1897, NY. Married in Ireland ca. 1836, emigrated 1848.
2. Elizabeth Kennedy, b. ca. 18111 Ireland, d. 23 Nov 1897, Cleveland, OH, married to Carter Pears, 14 Mar 1842, Montreal, Canada.
Arthur is my wife's immigrant gggf. We are 99% certain that Elizabeth was his sister. We suspect that Elizabeth and Arthur were also children of Edmund Kennedy and Mary Hurley because, from 1856 to 1858, Elizabeth Kennedy and her husband Carter Pears live in Montreal at exactly the same address in Montreal as Daniel Kennedy and his wife Bridget McNerny.
A marriage record for Arthur Kennedy and Catherine Griffiths should exist in Tipperary.
