Does anyone know of any "Ryder" families in the Beara area in the 1820s? I have been trying to gather information on my great grandmother, Mary Ryder Sullivan, and her husband, Patrick Sullivan. Their son, Jeremiah was born around 1823 and came to the United States about 1850. His first citizenship papers filed in Albany, New York in 1852 indicate that he migrated from Bearhaven. Family death certificates indicate that he was born in County Kerry Jeremiah McMahon
