Rea - George A and Edward R From County Down

Hello, I am new to Genealogy Wise and hope I'm doing this right.

I recently found that my x4 great grandfather George A Rea (1803 - 1853) was born in County Down.  He came to Paterson, New Jersey on May 24, 1817 and received his Naturalization papers on January 23, 1826.

George married Margaret Ann Rutherford around 1830 in either Philadelphia or Paterson, New Jersey.  George and Margaret settled in Paterson, New Jersey had 9 children beginning around 1830 and both died there, George in 1853 and Margaret in 1855.

George had a brother named Edward R Rea that was born in 1795. 

Their father may have been named John, but I'm not sure about that.

I'm hoping someone may be able to provide additional information.

Thanks,

Scott
