James McMullan

Hi all!  Found some new information about ancestors from another part of my tree.  James McMullen (1816-1876) and his wife Mary Jane McDonnell (1820-1869).  They were married on May 1st 1842 in Down and Connor parish Layd, Antrim.  Their son Patrick was born in November 1842 and they immigrated to the U.S. in 1843 arriving in New York on September 5th.  They later moved to the Philadelphia area.  I was hoping for any information on their families if possible.  As always thank you for any help you can provide!
