Because our grandfather, Eugene Lynch, is such a mystery to us we really don't know how to find him. All we have for certain is the 1910 census [lines 39-43]. It says he came over in 1887. The story is this: Eugene married my grandmother in San Jose in 1904 and they lived in Sacramento. He abandoned her and their children in 1909 [sic] when my grandmother was pregnant with my father. We didn't really know anything about him until we started doing this genealogy. We knew [sic] he died in San Francisco in 1917 but were surprised to discover that he was the captain of a schooner at the time.

That day was the highlight of our trip to Ireland, and for me it was an unbelievable gift. I have been wondering and imagining for so long about my grandfather's (and thus my own) origins that I still quite can't believe I went there. It was a profound and moving experience for me. My sister Pat and I speak of it often ... It was magical to us. Both of my parents were from families who didn't stay connected with their homeland, and this journey has really fulfilled a need that I hadn't realized I had. I'll be forever grateful to Tom Kearney for introducing me to you, and to you for so generously sharing your expertise with us.
We could trace our roots from the time [my great grandfather Thomas Lynch] landed in New York state in the early 1850s; before that, we have nothing solid. Family folklore has it that his parents were a Michael and Mary in Ireland. A bit of searching I tried to do while I was in Ireland some time ago led nowhere, so this news is encouraging.
