The records I have, show Margaret Dooley daughter of Michael Dooley (farmer of Tomemace) and Bridget (Known as Delia) Hardiman as born on 23 July 1918. Bridget (k/n Delia)Hardiman was born 3 December 1891 married Michael Dooley at Annaghdown on 27 October 1910. Bridget Dooley is the eldest daughter of Patrick Hardiman (Hagadon)1847-1817and Bridget Small 1864-1932.
I have copies of a number of different certificates plus a family tree which maybe of interest to you.
My E-Mail address is email@example.com . If you send me your Email address I will Endeavour to scan what ever info I have which you are interested in. From what you have said above I am reasonably sure we are talking the same family inspite of birth date difference.
