re Gallagher Family
I looked at the 1930 US Census for New Jersey, Essex County, West Orange District 0637 Town ED 7-621 SD page 93. There is a James Gallagher with a wife named Winifred ( although it was spelt incorrectly by the census taker). Both were born in the Irish Free State. He said he was 66 at the time of the US Census and that he came to the USA in 1880 and that he was naturalized. She came to the USA in 1884 and was also naturalized. It says that both of them were age 24 at the time of their marriage. They and two adult children were living at 42 Columbia St West Orange NJ . Could this entry be your family? If so I will see what else might be available. Besides Death records their parents names might be marriage record both religious and civil. Their naturalization records and might give you Winifred's maiden surname and her parents name All the Best,
