Basically, the northern Italian merchant states like Venice/Genoa had a lot of crypto-jews in their ranks. These people went north to the Hanseatic states, and traded there. Also England in-between William I and Edward I was full of jews, and so when parts of England joined the league, many jewish merchants likely got to the Baltic via England. (William himself was jewish, not Norman by the way, he was an "illegitimate" son of the duke and a tanner, but the Latin word for bastard was the Hebrew word mamzer back then, meaning his mother was a jew).
