Sealy Family from Cork

[Moonshine58]

Hi.  I am trying to find more information about Richard Sealy and his wife, Elizabeth. I am guessing his DOB is about 1820.  All of the information I have is he was born in Cork and possibly immigrated to the US. 
He married a woman named Elizabeth, no further information. 
Their children are:
Susan - born in Bandon 1842, immigrated to New Zealand
John - born in Ireland 1844, immigrated to US
Joseph - born in Ireland 1846, immigrated to New Zealand
Thomas - born in Cork, immigrated to New Zealand
Richard - born in Cork, immigrated to US
Francis - born in Cork, immigrated to US

Thank you for your help, it is truly appreciated.
