The grandson Vincent McDonald is my great uncle, brother to jean mcconald smith, my grandmother and mother to my Dad, Herbert Francis McDonald. I haven't been able to find the link between wright and McDonald. I know my dad's birth was registered in Sydney, but he was raised by the Wright's in Point Typper, ns born 1927 died 1985. Vincent McDonald grandson lived in pennsylvania and was married to Sue. Most of the Wright children lived in the us when they became adults.
