Malky already tried..... not the same according to my great Aunt Mary.........
George Corbet Wood married Elizabeth "Patterson" "Ross", 1923, St Nicholas, Aberdeen
Mary Rennie Patterson Wood born 1923 St Nicholas, Aberdeen. (Middle name link "Patterson") She passed on in 2008 in Aberdeen, so that eliminates her, due to the Canadian situation.
Helen Howitt Wood, born 1925, St Nicholas, Aberdeen. (As per your own post.)
Ruth Cobble Wood born 01/12/1927, St Nicholas, Aberdeen. (Only birth of a "Ruth Wood" born between 1915 and 1940 in St Nicholas, Aberdeen.) Death, 02/12/1927, accidental suffocation in bed, 1 day old, father and mother listed as above, at 4 Darlington Place, West-North Street, St Nicholas, Aberdeen.
Mary Mutch Ross Wood, born 1928, St Nicholas, Aberdeen. (Middle name link "Ross")
I wonder if this is raising questions that are preferred to be left alone/unanswered. The accidental death of Ruth, may still be affecting the living who were directly related to her.
The only way to sort this out, is to go to a registrars and look at the parents of Helen Howitt Wood and cross reference them with Mary Mutch Ross Wood and Ruth Wood, as we know who Ruth's parents were. I also suspect that there are more children born post 1923.
