Hi Ves, This is a link to a site that may interest you.
http://www.ourroots.ca/e/ It's free and full of local history books. I did a Draudson search and not much came up, but the Cypress hills book showed lots of page numbers. I also searched using LATVIAN and 48 books show up, pay special attention to; OVERLORD of the LITTLE PRAIRIE, a report on Charles Plavin, lots of pages to click on. I also did a search using only LATVIA and 96 books show, but I didn't read any of them. Hope this helps with your project, Butch (board volunteer)
