Is there way to mark name which person used and was known. I have several persons in my family tree who use their middle name as their name they are known. Like let's take person called James Oscar Wilson who all know as Oscar when He lived but Oscar's descendants hundred years later couldn't know that and could easily think he was known as James if they just see his name written.
Sorry for bad description but so what is best way to mark name person used ? way that others beside me can also understand
