Interestingly, the 1860 census shows that Cornelius/Connel (Cornel) Haggerty had a neighbor in Rush Township, Michael Cassel, age 53, a laborer born in Ireland, who is the father of our great-grandmother Mary. The 1860 census doesn’t specify the relationships among household members, but Michael Cassel is living with people who appear to be his children: John 20, Mary 18, James 16, Thomas 12, Catherine 11, Ellen 5, and Elizabeth 2. (Mysteriously, Michael’s wife Elizabeth is not mentioned here.) It would make sense that Cornelius Haggerty introduced his brother James to his neighbor’s daughter Mary Castles, whose age corresponds to that of James’ future wife. Also, Mary’s youngest sisters are surely the aunts Mary Kellington mentions, Lizzie Castles and Ellen Castles. So these are our relatives.
According to the 1860 census, like their father Michael Cassel, John, Mary, James, and Thomas Cassel were said to be born in Ireland and the younger children in PA. This doesn’t jibe with the information on later census records showing Mary and all the other Cassel children as being born in PA.
In 1870 Michael Cassels 63 and Elizabeth [McCorkle] Cassels 50 (named as Hugh Haggerty’s godparents at St. Patrick’s in 1879)) are living in Kline Township with their children James 26, Thomas 23, Ellen 15, Elizabeth 12, and Annie, 9. (Their daughter Mary, our great-grandmother, is living nearby with her husband James and their children.) In 1880, Michael Castles 75 and Elizabeth Castles 60 are living in Old Honey Brook, Kline Township, with their children James 36 and Annie 20. At this same time their son Thomas Castles is also living in Kline Township with his wife Margaret and their son Michael, age 1.
In addition, I found listings for John Cassels, Mary Castles Haggerty’s oldest brother, born in PA in 1840. In 1870 he is living in the largest nearby city, Wilkes-Barre, PA, with his wife Bridget and their children Jane 5, Julia E. 3, Michael 2, and James 6 months. In 1880 John Castles is still in Wilkes-Barre with his wife Bridget; the family has expanded to include Jane 15, Julia 14, Michael 12, James 11, Thomas 9, William 7, and Charlotta 1.
The 1890 Federal Census Directory for Kline Township shows Thomas Castles 42, a laborer, living with his wife Margaret and their children Michael 14, John 11, and Margaret. There is a separate listing in this same directory for Elizabeth Castles, Thomas’ mother (and the mother of Mary Castles Haggerty), now widowed. After 1890 I found no information on the Castles.
