My father passed away when I was pregnant with my daughter but I had her name picked out so I didnt use his name when she was born. Also I knew I was going to have another so I wanted to see if I had a boy next to use it.

If we have a boy its easy but if we have a girl I'm going to have to feminize his name, which is fine as there is feminine version already but I cant decide on the best spelling.

Which would you choose? If it isnt obvious my father's name was Karl. I have an idea of which I would choose, and I know my husband will let me have whatever I want, but would love to see what others prefer.

Edited to add this would be a middle name. If I have a son his middle name would be Karl and same for a daughter.
