Robert Macfarlane who died in Kaniva in 1908 was married to Susanna Roberts, His Mother,SUSAN Macfarlane was married to Daniel Macfarlane, Susan's maiden name was Mckie.
Daniel was married before what we understand is that Daniel lost his first wife, Robert the eldest child that died in 1908, he actually died 3 years before his mother/ stepmother and may have been from the first marriage, if this is true, then all his siblings were half brothers and sisters.
The is a few more children that I have found on my family tree that I got from my cousin in Ireland, I will give you these a bit later.
I do hope this will help you with your inquiries.
Robert ( Bob ) Mcfarlane
