Have Grandchildren of Famine Survivors Lived Longer?

Articles have begun to appear in science journals about the field of epigenetics whereby extreme experiences by an earlier generation can effect a current generation's genes.  This article describes research around a famine in Sweden.

Does anyone know of research done in Ireland about we who are the grandchildren of men and women who lived through the famine?  I'm lucky to be 78 with brothers 85,88 and 91.  We would find the research very interesting having had a grandfather born in Connemara in 1850.
