John Mullin born ca 1839 probably in Ulster somewhere. Married Anna Gribbin born ca 1844 also probably Ulster. Their first born, Elizabeth was born in England in May 1867. They emigrated to the USA, between May 1867 and Feb. 1872. Their 2nd born, Mary was born in Pittsburgh,Pennsylvania, USA Feb. 23,1872. They had a total of 7 children. Anna reportedly died not long after her 7th child was born in Dec. 1881. The family then settled in Dunbar,Pa., where John was a coal miner. How do I find where John and Anna originated?? How do I determine which John Mullin is mine ?? The name Mullin is spelled many ways, as is Gribbin. Any help or suggestions greatly appreciated. Tom Maher
