I have my Grandfather Walter Thomas Roberts b.12 Aug 1897 I believe in Tottenham. I believe he lived at 24 Newton Rd. He married Annie Ellen Eaves b.11 Oct 1897. They were married 6 May 1917 at St. Lenord Parish, Shore Ditch County in London.
Sorry for the late response; I just happened to be doing a google search for blonar infomation when this post came up. I believe Blonarovich is Austrian; but I can't be sure. As for my family; they were all (as far as I know) in the Manitoba area (around or near Winnipeg).
The way i did it was got my brothers,sister and parents to see how far they could go, then i got help from the grandparents and i got back prety far, im now in the proccess of a more 'in-depth' reasearch.Hope this helps a bit.
