Jean,
For the record, although you probably know this, you've mixed up the prior generations in your post.
William George McADIE b 1867 was the son of William McADIE born abt 1830, Wick, father a farmer, called George.
It was William, b. 1830 who married Sarah Jane ABBOTT.
Father George may, or may not, be the George married to Elizabeth ROSIE, one of my lot.
However, there is another William in Ararat yet to be eliminated from inquiries.
