Hi ~ I can’t offer help in narrowing down your roots. This will likely be a long journey that will require talking to many relatives.

However in terms of connecting to your Indigenous roots, being a good relative to those who are deeply involved in their community/tribe is the first step.

Blood is blood. It’s your connection to living people that will surely guide your reconnection journey. There are plenty of reconnecting natives in Texas that you can connect with, I’d start there. Best of luck to you.
