Hi Kathleen,
After much effort, I did manage to locate the surviving family of Annie Jermyn--and this was a tough nut to crack--there were many times in the course of a couple of years that I thought my search was going to Jermyn-ate (sorry!)--but it sometimes seemed as if they had disappeared from the face of the earth. Finally, I located Edna Draper, daughter of Mary Grace Jermyn Draper, who was Annie's older sister. Edna is now in her 80's but she was the key that opened the door. Annie lived with her mother in Lynn, Massachusetts when she first arrived in the United States. I was able to glean the story of what happened to her after Titanic and, like so many of the other survivors, it is a sad story. Within days now, Senan Molony's new book "THE IRISH ABOARD TITANIC" will become available and Annie's story will appear as well as a good photo of her. I hope you understand that I need to defer answering your question so as not to "scoop" the book for the moment. Bear with us, after several year's research, the time is very nigh.
Who are the other Irish passengers you haven't accounted for? My biggest nemesis was Norah Murphy--found some good info on virtually all the others but she eluded me entirely. In the United States (where I myself did most of the personal contact with family members) we got great cooperation with all we contacted with the lone exception of Bertha Mulvihill's family who did respond but advised that they were "Titanic'd out." (Senan had great information on Bertha anyway and I had met some of her relatives in Ireland when I visited there in 1998). But we did have very good cooperation on the part of the family members of the McCoy siblings, Thomas McCormack, Ann McGowan, Mary Agatha Glynn, Helen Mary Mockler, Ellen Corr, John Kennedy, Hannah Godfrey O'Brien, Bridget Delia McDermott, Annie Jermyn, Kate Connolly, Katie McCarthy, Kate Gilnagh, Anna Kate Kelly, Helen Shine, Minnie Coutts, James McGough, Kate Murphy, Margaret Murphy, Maggie Daly, Eugene Daly, Hannah Riordan, and others (including families of those who were lost in the sinking). Although I did track down the present whereabouts of Patrick O'Keefe's son Edward, and all of Edward's daughters, I did not contact them personally at any time. I did, however, spend more money on O'Keefe research than I did on any of the other Irish survivors insofar as obtaining documents and pertinent biographical information which have resulted in a superior outline of his life.
Once the book is launched, I'll be glad to go into detail as to every step I took in the process of locating the surviving family members should there be any questions about that which arise.
My best,
Phillip
