John Moran : Short Biography

I am looking for the parents of my 4th great grand father. John Moran (1829-1890). Through my ancestry research it looks like he was born in Parish Grange Tipperary.

His siblings are James (1818-1872)

Maria "mary" Flynn (1820-1872)

Jeremiah (1824-?)

Lawrence (1835-1917)

Catherine Bridget "Kate" Reagan (1838-1913). 

They immagrated to the united states around 1850.  John married an Anne (1832-1927) possibly Kennedy from Limerick.  Not sure if they were married in Ireland or the states. Any help finding his parents would be greatly appriciated.  I would also love to know if there are any living relatives in Ireland.

John and Ann had 7 children

Bridget

Lawrence

Catherine
