I recently decided to seek dual US-Irish citizenship which requires a proven pedigree to a great grandparent born in Ireland.  I decided to try working with an accredited genealogist in Ireland: Genealogy.ie.  Jillian van Turnhout found where my great grandparents were born and baptized, their parents and the witnesses to the baptism!   The speed, accuracy, completeness and professional curiosity of Jillian’s work bordered on outright sorcery!  Even better, her fees were quite reasonable.  I would strongly recommend to anyone seeking to explore their Irish ancestry that they contact Jillian or one of her colleagues at Genealogy.ie!
