Red River Ancestry

On the page for Francois Mercredi (1832-1900) there is reference to daughter Harriet (Henriette) who married Joseph Hourston, an HBC Post Master from Ireland.
HBC records him as being from Evie, Orkney, and not Ireland, and I can confirm this, as he is in my Family Tree.
For those who may be interested, he was born 25 Sep 1849 at Ploverhall, Evie, Orkney, to parents David Hourston & Mary Harper, also from Evie. Not sure when he died but it was about 1912 in Manitoba. I have his ancestry back to William Hourston from Sandwick, Orkney, c. 1743.

Please do not create new Forum Topics where the topics already exist. It causes confusion and duplication.
I will move your comments to these pee-existing Topics. Thanks.

My apologies Gary,
While I'm very familiar with family genealogy research, I've never used forums before, and therefore didn't fully understand procedures, but now I've got the general idea of using 'existing' topics for comments. Thanks for the guidance, and for transferring my comments to the appropriate topics.
