My name is Dale Neily. I am now 71. I live in Ontario Canada. My father, William Neily, had two brothers George and Cleveland and four sisters. My uncle George Died in the 1950's in British Columbia. My uncles George and Cleveland as teenagers travelled west and worked inBritishColumbia just over the broder from Washington State in Canada. There are a lot of Neily family of these two uncles still living in British Columbia and I was thinking that perhaps my uncle George may have been your grandafather? If interested contact me by email at firstname.lastname@example.org and I can give your more details of that line of the Neilys. All the Neily's originated in Nova Scotia coming over in the 1700's.
They spread from there into the United Staates and across Canada. It does not surprise me that there may have been native and French Canadian marriages or relationships. You may be decended from the western Neily who travelled west in the late 1800's.
