Kiltaglassan Thank you for the information I will go through them but I think I already have researched those links

Mr J T Arthur
I wonder why James Cahill used the name Carrol research is almost impossible when that happens. I also wonder why James Cahill returned from the USA, I would be interested in reasons if you know them.
I need to look at Catherine Kate Butler b 06 Nov 1915 in Kidare today, her father John Butler born 05 Jul 1880 in French Fuze (son of George Butler and his second wife Catherine Gorman) on Catherine Kate Butlers birth certificate he is listed as a soldier, Johns wife is given as Bridget Connors. On Catherine Kate Butlers marriage certificate she is listed as Living in Hybla and John's occupation is Labourer. Now I have the trunk of the tree I need to spread the net a little wider and see if John and Bridget had any other children.
Unlike YDNA, Autosomal DNA is passed down through the male and female side, even though I have a connection with the Butler surname that may be a red Herring and the Autosomal DNA could have been passed down to me from a Cahill, Curran or Broughan etc.
