Cronin is a very common surname in West Cork and Kerry in the south of Ireland.
My grandfather was from Cork and was a Sergeant in the RIC ( Royal Irish Constabulary), which was the police force in Ireland until the foundation of the Irish Free State. He died in April 1947.
He had 1 brother, who was a Franciscan friar.
It appears that we have no apparent connection, but who knows.
