Her name is Bridget Cassidy.  I have her DoB as 5th Feb 1874 - This is from the 1939 register.  The only tie I can find is a Bridget Cassidy born Holywell.  BUt as I said she always told family here she was from County Cavan.  If this is the right record I can find records of siblings being born in County Cavan.  So I am thinking that the family moved slightly south around 1877/78.
I am not sure what you are referring to when you ask for the SRD?  Will happily supply if I have it -once I know what it is!  Many thanks Sian
