Novogorod is the first Hanseatic world you'll probably bump into at approximately 150 light years (at least five jumps) from Nueva Castille. You'll have to put up with League authorities there.
St. Jean is approximately 200 light years (at least seven jumps if not more) spinward (galactic east) of the Nueva Castille. Going there takes you the Clan Invasion Corridor of course.
Either way I'd say your looking at 6 to 8 weeks at best to civilization.
