Susan McNamara was the sister of my forebear, John McNamara , born 1832 Miltown Malbay, died 1918 Melbourne Australia.
The parents of John, Susan and several others, some of whom may not have survived the great famine, were Francis McNamara and Honora McMahon.
Some of John's siblings set up long -term connections with the US. Miltown Malbay has remained as the ancestral territory for the family, a place for travelers to go on pilgrimage.
We have a list of the various descendants from the Bog Road families, Sexton, Kellys, Sullivan, Goonan and White. I think it must have come from some of the US McNamaras , though I'm not sure. It is not dated and is a bit short on dates, but it includes the descendants in Ireland and the US. It runs, of course to quite few pages.
In 2009, 150 years since his arrival in this country, we published a book of the stories of the first Australian generation, which also links back to continuing Irish connections in Miltown Malbay and Kilkenny, his wife's birthplace. (The McNamara Meany Family in Australia 1859 - 2009, available on e-bay. Further details if you like. )
It seems likely that we have common ancestry. With good wishes
