Catherine Wright born circa 1840 married Richard Britt 27 February 1859 in Ballingarry, County Tipperary.  

Catherine and Richard had three sons born in Ballingarry:  William born circa 1860; James born circa 1862 and Richard born in 1864.  The family moved and settled in Luzerne County, Pennsylvania.  They had two more sons:  Patrick born circa 1867  and Michael born circa 1870.  

I don't know what happened to her husband  Richard Britt.  I know that in the 1880 US Federal Census for Luzerne County, Pennsylvania, Catherine had remarried to a man by the name of William Kennedy and they had two children: John born  circa 1875 and Johanna born circa 1877.  

The 1880 census listed William, James, Richard, Patrick and Michael with the surname of Kennedy.  This is wrong; their surname is Britt.  The only children of this household with surname name of Kennedy are John and Johanna.
