I'm sorry to say, but I still have not located any information on John McKechnie after 1888. All I know of him is that he was born in/around Paisley, Ontario about 1863--give or take a couple of years. His older siblings left Paisley as they married and move to Chippewa County, Michigan in early 1880s. Parents and younger siblings arrive same location by about 1883. Parents both died in 1888 at Sault Ste. Marie, MI. Father was Donald Alexander McKechnie and mother was Mary. Her surname was likely McArthur, but could also have been McCarthy or another name with similar sound.
What do you have on this W. J. McKechnie that prompted your inquiry message?
It sure would be great to finally locate "my" John!
