I don't doubt someone will use our names at one time or another! We don't have very unusual or unique names. For me if someone has the same name as my children I would either see it as a compliment or that someone has a great taste as me hehe, honestly I wouldn't mind. I don't have a monopoly over these names.
The only reason I would not disclose the names we have chosen is because I don't want to hear negative comments, particularly from my mother. She has alreasy turned me off two names I had chosen for this bub, so the names (Emily Louise and Dylan Matthew) we have chosen now are staying under wraps to her at least!
