My only information that I have on this family is as follows;
John Riordan b 1831 in Ireland d May 6, 1876 in Easton, Bristol co., Massachusetts and on his death certificate lists his age as 44 and his father was Jeremiah Riordan b in Ireland and mother was Honora Barrett also born in Ireland.
doing some math makes Jeremiah b abt 1783 and Honora b abt 1800
In searching Co. Cork where I have been told they came from I did find so many Jeremiah Riordan's and a few Honora Barretts.
One thing I did find was that their was a John Riordan age 24 Ireland to USA June 13, 1856 and Jeremiah was b 1858 in Ma.
