There is only one O'DALLY listed on the genealogical map I purchased in Ireland and it is in Galway Co. There was a Dally family from France who lived there, a Ceasar Dally of Paris, France who lived there with his aunt. His family crest was written asForte Et Vite ("Swift and Strong") and in Gaelic Laudir Agus Mir as the O'DALAIGH crest is worded. The source of this information is from James D. Daly, Esq. account copied by his son Dermot J. Daly of Castle Daly, Doughrea, 18th Oct 1936. It is in a booklet on the O'Dalaigh Family. There is a DALLY castle in Scotland and I will have to search my papers to find out where it is located. Someone in IBM sent info to me a few years back. I shall forward it to you when found. Tom Dally P.S. I don't know where Port Arlington, IR is located.
