FAMILY RELATIONSHIPS

Capitalize familial names when the relationship is considered part of the personal name or when the relationship alone is used as a proper name:

            Uncle Bob

            Cousin Snowie

            Mother, Mom, Father, Dad

            Godmother

Do not capitalize the family relationship when it is preceded by a possessive pronoun:

            her cousin Snowie

            my mother

Set off the name with commas when only one person bears the relationship:

            his son, Robert, came too (only son)

            his son Robert came too (more than one son)

            my wife, Michaeline, came too
