Charles Cassidy : Short Biography

I have traced my Cassidy family to Ballyboughal, County Dublin in the 1800s.  I am seeking birth/baptism records and a marriage record for Charles Cassiday (1800-1862) and Catherine Corbally Cassidy (1812-1873).  They may have come from Kilmainham Townland area, County Meath.

This is what I know for sure:

My Great-Great Grandparents:

Charles Cassidy (1800-1862) and Catherine Corbally Cassiday were in Ballyboughal, County Dublin in 1832-1838.  They had six children:9 Feb
