Hi Derek,
Thank you for your reply and apologies for late response, we had a long weekend here and were away.
I am going to commence searching the Parish records in Rothesay, Bute area and hopefully come up with something for my Grandmother Margaret Ann McLean, as on her wedding certificate 27th April 1928 she and her mother Margaret McLean have the same surname, which on further research mentions; if a child was born what was then termed 'illegitimate',he/ she would be indexed under both the mother’s maiden name and the father’s name (if known). Which is starting to make sense, as my mother Agnes Miller Mackay b 24th May 1939 and passed in 2012 mentioned, if my memory serves me correctly, that her mother was brought up by two elderly aunts, so I will commence on the census hunt also.
Thank you again Derek I appreciate all the hard work you have done.
Irene
