I have now been informed as a result of a conversation between my friend and her aged aunt, that two of the O'Sullivan girls were called Nora and Bridget. Where they came position-wise in the 11 children I have no idea. The other snippet picked up from the aunt was that Mary O'Sullivan's father Timothy was deceased prior to Mary coming to England ion 1917/18 - not long before, maybe 1916/17 ? This would mean that with Mary being born November 1900 and her father dying 1916/17 that 10 of the children would have been born 1901 - 1916. Hope this extra information helps. I am still searching. Thanks.
