Is anyone else the Celiac trailblazer in their family?

I see so many posts saying “my aunt, my dad, my cousin, my brother, etc” all have celiac disease. I am the only one in my family that I know of…. Diagnosed at 27. It’s gnawing at me that I don’t know anyone else in my family who has it. Both of my parents were already tested. My siblings were not (they refuse). I feel so alone in this. I feel like an outcast next to my family. My aunt has MS and also eczema so I feel like she might have it? I just don’t understand how I’m the only one so far. Does anyone else experience this??
