I have tried to find this one thing out and have not been able to about the name Liam~ I want to know if this is a nickname such as Bobbie is to Robert or Cal is to Calvin? This name is rising in popularity here in the United States but do not know what type of name it is considered overseas in England, Scotland or Ireland. Just wondering if anyone knows anything about this name. I really like it but do not want to give my son a name that would be considered a nickname. Please respond ~ Thank you!
