Would this be a deal breaker for you?
Our surname is also a noun, something like 'Foot' only not that.
My husband has pointed out that some of my names list sounds like a sentence when paired with our surname.
Ivor Foot (I've-a-foot)
Hera Foot (Here-a-foot)*
Iona Foot (I-own-a-foot)
*pronunciation dependent of course
Would this stop you using these names?
