Alexandbrook which I guessed as Alexandrowsk(from the handwriting)in Taurida
As per following site, looks like Alexandrowka.
Crimean Taurida Regionhttp://www.blackseagr.org/pdfs/village_list.pdf
According to list in link above, colony was called Michajlevka or Michaelsdorf in (Crimea) Taurida.
I am going to GUESS and say it was Michlowa > Bialostok > Poland (bordering Belarus today) on the way to Libau (popular port w/Russian Germans)> Liverpool > Canada.
