Is there anyone out there in the GT-verse that has adopted? Specifically Catholic adoption? Anyone with mixed-race adoption stories?

I'm not ready to write about it, but let's just leave it at this: the Captain and I want to get started on the adoption process now, but we have no idea where to start and could really use some advice from People Who Know™. We have decided that we want to adopt a newborn/infant first and are holding off on foster-to-adopt until we have a home/yard/more space and time to devote to older kids, and ideally want to be in an even more stable place in our lives before we welcome kids from that...errr...pipeline? I don't even know what to call it sensitively.

I still have the links to a couple of FB pages and such that people sent me awhile ago, and thank you for those. But...where do we even START? Should we talk to a lawyer first? Find an adoption agency we like? Do we go to more than one adoption agency? How much money should we have saved first? Thousands of questions.
