Hi Wini.
No luck.
Bear in mind it's nearly 5am where I am so brain not at it's best
I've been having a play, trying to find Agnes McDonald. You've obviously
been looking for a while but I thought, beginners luck etc....
Nothing obvious.
I did find a marriage in 1921 Agnes McDonald c1901 to a Peter McLaren Gunn c1903
(thought I'd cracked it when I saw Peter Gunn, Williams son's name)
However, Peter's parents Robert William Gunn and Helen Mason.
Also found death in 1920 of a Agnes McPhee c1886 wife of John McDonald
Agnes' parents Alexander McPhee and Magdeline Blackwood.
Nothing obvious to link either of these to your family.
Am I correct in saying William's parents were John and
Bessie Gunn and Annie's parents Peter McPhee and Jessie MacKinnon?
