Looking for information on Henry MCCAFFREY and wife Elizabeth MCKEE who immagrated from Ireland and settled around Buffalo, NY sometime in mid to late 1840's. They had at least 2 children named Owen MCCAFFREY born about 1851 and Margaret MCCAFFREY born about 1849 in Buffalo. Both Henry and Elizabeth passed away within days of each other abt 1854. The 2 children moved with grandmother Bridget MCAFFREY to Dubuque County, Iowa in late 1854. Anhthing helpful. Thanks in advance.
