Sadly I don't have any further information that could help you. The only link between my own family and the United States is that my great-grandfather was born in Brooklyn, possibly in 1852, but I know that both his parents emigrated shortly before that and that they all returned to Ireland when my great-grandfather was only 6. So I cannot imagine any link between my own fmaily and the state of Iowa. My interest in the John J Fogarty on the Vietnam Wall flows from the fact that that is also my fathers name, and I though it both interesting and a source of pride that my family name should be represented on such a great American momument. You probably know this already, but the Fogarty name originates and is found it its greatest numbers in north County tipperary, Ireland, where I come from. The town of Thurles in particular has as the coat of arms of its Urban District Council the coat of arms of the Fogarty clan.
