I am researching Patrick BRANNIGAN born in Ireland abt 1850 and married to Margaret MILLER who may have been from the North of England. Patrick moved to Shotley Bridge,County Durham England before 1880. In 1881 the family lived at Twin Coal Row, Black Hill, Benfieldside Co. Durham with a brother Bernard born abt 1862 and a cousin John born abt 1851. All were Iron Workers. Does anyone know of or have connections to these family members?
