I found 2 ways to check on the spelling.
The first is >from the monument company where I ordered my mother's
gravestone. They can help with standard spelling.
The second way is when I mentioned to them that I've heard my mother's
father was a kohan, but was never able to confirm it. The man taking my
order suggested checking her ketubah (which, luckily, I had). Not only did
it confirm my mother's hebrew name, but it listed my grandfather's hebrew
name followed by "the kohan"!
Hope this helps.
