Good lord, I had both of their wiki pages open, and STILL somehow D and G were the same letter in my mind.

Perhaps you suffer from D-G letterblindness.

It would be totally understandable for someone who reads handwritten Russian to confuse D and g in their mind.

Oh man, I don't think I've written cursive Russian in something like a decade. I honestly have no idea how Russian historians parse old documents; old hand-written English is hard enough, but cursive Russian is a whole other thing.

My last name just looks like a child drawing a wavy ocean!

He gone doofed.
