I believe Rose may have been born in 1926 under the name Roseann Docherty McGinnigle. This information is on Scotlands People, and she was born at Calton, just like you said. I believe this is her.
There is then a marriage in 1945 of Rose Ann McGinnigle to a William McIlroy Williamson at Provan in Glasgow. Do you think this is her marriage?
They may have had a child - Rose Williamson, born 1945, but I am not 100 per cent certain about this child being hers... only certain that a child of this name was born in 1945.
You say her parents were Robert McGinnigle and Agnes Blyth, so I think she was born as McGinnigle but with the middle name Docherty.
She then dies at Dennistoun in Glasgow (not far from Calton) at the age of 34 in 1961, according to Scotlands People. She dies with the name Roseann Docherty McGinnigle Williamson.
Hope this helps,
