searching for info on Edward Riordan county cork

hi there,

my grandfather was Edward (ned)Riordan. He was born 1922 in cork. Married to Ina Woods.

his father also same name born 1892 married anne O'Connell

and his father again, also same name, born 1842, married Hannah (hanora) Crowley

On the wedding cert of the last Edward it says his father was john. im very curious to find any of his siblings and his parents and where they lived. mostly over the years the families seemed to live in and around Douglas, in Cork. I think Hannah was from Carrigaline so they may have lived there also.

And also,Edward 1892, Looking for his siblings also. i have found some, Maggie,John, ellen, Laurence, mick, annie, Mary and phil. unsure if there were more.

Thanks in advance
