Thanks Lisa!
I made a couple of mistakes though, Jessie Casement didn't die during childbirth, she died from Phlebitis which was brought on by childbirth.
Also William McDougall her son died in 2004.
Like i said I don't know a lot about the lives of David McDougall and Jessie Casement and I'm not sure when they were born, William McDougall their son was born in the 1920's so i would guess that Jessie and David would have been born either in the late 1800's or early 1900's. As for when David McDougall died my mum assures me that he died in the 70's, she's not sure of the date but that it might be 1972.
What i do have however are a few family photos of my grandfathers which we came into possesion of when he died.
Below is a picture of my Grandparents William McDougall (David & Jessie's son) & Janet Moore, this was taken on their wedding day in the late 1930's William and Janet are in the back of the picture, the woman to the left of my Gran is Sarah McDougall (William's sister) the man to the right of my grandfather is Mick, Sarah's husband.
