Denis O'Keeffe From Newecastlewest, Ireland

Denis O'Keeffe and his Wife Mary Gorman had six children, Bridget 1833,John 1835,Daniel 1838,Catherine 1841,James 1844,Ellen 1848.James left Ireland in 1860 for America and John came later. I have no idea about the females as they probably married and changed their names. Denis was a "horseshoer" and lived on Maiden St. in Newcastlewest, County Limerick.Denis was my Great Grandfather and all the interim decendents died before I got Interested in Genealogy. Any information will be greatly appreciated. I went to Ireland in 1999 but could not get any information that I did not already have. All responses will be acknowledged. Thanks. Joe
