Ryder is the name I inherited from my father, who was an orphan, and adopted by the Ryder's.  I never wanted to change it.
My mother was given a last name at birth that didn't belong to anybody in the family. Until recently I thought my grandmother had named her after Samuel Clemens. Now that I've done research I know the truth.
Before I ever started research on the family tree, I knew very little about my cousins, grandparents, aunts and uncles, apart from one small branch of the family. Whenever a doctor would ask about my family medical history, I would wave a hand saying, "Oh no, in my family there is no history of ____________ (fill in the blank: heart disease, breast cancer, glaucoma...) whereas in fact I didn't have the slightest idea.
So discovering/ building a family tree is mind-blowing. It hasn't contributed much to my knowledge of family medical history. (In that area I'm not really looking for answers anyway.) Recently when the question came up, I said, "Well I only know one grandparent out of four. Can that be of any use? " You know what, in some cases, it can be useful.
But mostly doing this research is great for widening perspective.

It may be possible to confirm family relationships by comparing test results with C or other carriers of her ancestors' mitochondrial DNA.
Mitochondrial DNA test-takers in the direct maternal line:
Family Tree DNA mtDNA Test Full Sequence, haplogroup J1b1a1a, FTDNA kit #743050
It is likely that these autosomal DNA test-takers will share some percentage of DNA with C:
