My husband and I were just discussing this in reference to
Edwin and
Edmund. I can't stand
Ed or
Eddie. It seems like this comes up frequently but I can't think of many now.
David - don't like
Dave though
Davy for a youngster is cute
Douglas -
Doug and Douggie are awful though that wasn't the dealbreaker. I would still love to use this name, but in my family two bearers had tragic deaths.
Many I would never consider because of the common nn. Don't care for
Sam,
Bill,
Bob...
I do like
Jillian nn
Jill though. It's at the top of my list though I'm lacking in girl names.
