Children of John and Henrietta (Findlay) Turner

There were six children with the Turner surname born in Kilfinan, Argyll between 1927 and 1936:

• Henrietta Turner (born 1927)
• Alexander Campbell Turner (1928-1990; married Catherine Petterson)
• John Mitchell Turner (born 1931)
• John Turner (born 1931)
• Alistar Findlay Turner (born 1933)
• Ann Ysobel Turner (born 1936; married Robert William Blain)

However, I do not know which ones were children of John and Henrietta (Findlay) Turner and which ones were children of John's brother.

If anyone knows more, I would love to hear from you.
