I feel lied to

So for starters, all this info was me finding it myself, my mom believes dna tests are evil through conspiracy theories so all of my info has been 100% me and through certain apps that don’t have dna testing that have helped me.

So basically i started my tree simple, my parents and grandparents on one side are living so i used their information. So i was born into a german family (except my grandma she married in) i had their last name until i was 13 and was adopted. (saving the details but it was the best thing that ever happened to me)

So when i was little my grandma told me we were also french on her side but never said anything more than that , i brushed it off, now that ive been researching her side her father was litterally a 1st gen french immigrant and i never would have known if i didn’t research.

I was reached out to by a distant cousin who wanted to talk to my grandma because she’s the last of her siblings. I told her where i met this cousin and she agreed to speak with her.

After that she told me everything was right and she actually went to that part of france and experienced their life?

I’m not mad i’m more french than german, im just mad i spent all these years not knowing until my research and now i feel confused after leaning german for 6 years if i should have been learning french?
