Hi Tricia and Penny.
I am also tracking this family because I have a connection to the Normoyle side of the family.
John Halpin and Mary Anne Normoyle had two sons who are of interest here - John Halpin who Tricia is descended from and Francis Patrick Halpin who married a Margaret Normoyle in Sydney in 1889.
Margaret was the daughter of David Louis Normoyle and Alicia Barry. She was born 24 Feb 1864. Her parents were married February 1862 in Croom, Limerick. Her mother died and her father remarried to a Mary Ann O'Donnell. They had a second family, some in Ireland and some in Australia. From the dates of birth of the children I would guess they emigrated about 1883. The entire family (from both the first and second marriage) appeared to have emigrated to Australia. I have David Normoyle's parents as Thomas Normoyle and Ann Lewis.
David Louis Normoyle also had a sister Johanna who emigrated to Australia. She married a man called Michael Hayes in Croom too.(they are mentioned in his obituary). She died in 1918 - her parents are also given as Thomas and Ann(e).
My interest is the family story that my great grandfather, Thomas Normoyle - son of James Normoyle and Bridget Hannan (or Shanahan) who were married 29/2/1840 in Kilcornan Parish, Stonehall, Co. Limerick Adare. James and Bridget had nine children Daniel born 16/10/1840, Bridget born 26/1/1843, Michael born 4/1/1844, Mary born 28/4/1845, Margaret born 26/12/1847, William born 27/3/1851, Catherine born 8/2/1856 , James born December 12, 1858 and Thomas born November 28, 1863. They were in the Stonehall area which is very close to Croom.
Thomas emigrated to Australia (family history suggests with three of his brothers James, Michael and William and a cousin, David). This David is either David Louis Normoyle mentioned above or his son David. I am not entirely sure as you can see by the wide range of birthdates in Thomas's family he could be the cousin of either the father or the son. I have been in contact with another Halpin/Normoyle descendant who has done his DNA test - however there was no DNA match to my mother (who was born a Normoye).
I'd be interested to explore the connections further and to compare DNA if either of you have gone that far.
Kind regards
