Thanks Elizabeth. I realise now that I put the likely date (1830) of John and Jane Leggetts marriage much too early as they would have been married for 22 years before they had Jane and also a daughter Anne a year or so later in 1853! I think I should have said about 1850. There were at least two families with a John Legget as father, one was born around 1820 and died in 1875, he is not the one I am looking for - wrong occupation etc.. There were also at least two Thomas Leggetts in the area, the one you mention and another who is listed in the 1901 census as being born in Co. Wexford about 1854, could he be a brother of Janes? One of the witnesses to Jane Leggets marriage in Castleknock in 1875 was a Thomas Leggett.
