My Cornelius Duggan was in Durham (unmarried) in 1881. Do not know what happened to him, 1901 census may find him. Margaret Duggan (his sister) married James McCarthy and lived in Durham (Stockton on Tees), I bought a birth cert. for a Margaret Duggan (b.S.Wales in 1850) she was daughter of Richard Duggan so not "my" Margaret. Thanks for your interest and time.
