In my personal experience, IG isn't always equal to IC. So, depending on your priorities, you have a couple options (most of which, I think people have already touched up on).
If it's more important to you to have your IG-ness start in Gridania, start out as a Conjurer/Lancer/Archer, and play through 'til level 15-16, when you can access all the cities.
If the job is more important to you, go ahead and start as a Marauder in Limsa. After all, it won't be very obvious in game where you really started from, from an RP standpoint. On your wiki, you can still easily write that your character is from Gridania.
Just my opinion on the matter.
