Whether name is spelled Sanderson, Sandison, Saundersons, Saunders or whatever, the Alex b 1838 in Sprague & |Frye comes from p 181 of the 1870 census, as does his wife Mary Henderson (whose father was a Thomas! not a James or a Peter, as in various databases), and they were in St Andrews at the...

Sorry, I confused myself and you. It was a Maria Henderson and Alexander Sanderson to whom I meant to refer, and I believe that Alexander (who married in 1871, not 1875) is son of Mary Whitford and her husband George, not the son of this George with wife . Also, Maria Henderson's husband Alexander i...

the marriage of an Alexander Sanderson to Jane Atkinson was in 1871, not 1875, but that was not this man's son Alexander. There is much confusion on the internet between 2 different Georges - see these 2 links below, because I believe Jim Spence has it correctly (although I can find no support for t...

I believe that HBC biographical sheet claiming ca 1815 as birth for the George who was a carpenter in 1884 in McKenzie River district and who was earlier in English River is mistaken. This man was surely not working in McKenzie River district at age 74, and there is little reason to believe that he ...

I believe the William who married a Jane Atkinson was a half-brother, not son, to this George. Also, George's son Alex is not born in 1846 - he married in 1858. See

His age at death suggests he was born about 1810. He is very likely to be in the 1827 RRS census as the over 16 yrs of age son of a James Sandison who is shown as age 36, meaning born abt 1791, not 1780.

1870 census says that Mary Alder's husband William Sanderson was the son of a David Sanderson, and suggests birth about 1803. https://familysearch.org/pal:/MM9.3.1/T ... :942290293

He is very likely to be the George Sandison who had a son David born abt 1840, per 1870 census:

the James Sanderson shown herein as born abt 1780 was born abt 1791 (age 36 in 1827), and could not possibly establish Carleton House in 1795. Perhaps his father did, although his alleged father's HBC bio suggest he was at York Factory from 1779 to at least 1799, and then back in Scotland for at lea...
