Slattery Family of WI

I have been researching Patrick Slattery and his wife Mary Vaughn. They were born in Ireland. Patrick 1818-1884 Mary 1833-1907.

They lived most of their lives in Oshkosh WI. They had several children. They are also buried in a cemetery in Oshkosh. Mary had a few siblings but Patrick I know very little about prior to him coming to the US.
