topic suggestion for third course

Family relationships and names is pretty complicated in Chinese.  I would like to see a comprehensive lesson(s) covering this topic.  For instance, what do you call you older brother, younger brother, older sister and younger sister?  What do you call your father's older brother, his younger brother, his older sister, his younger sister, his mother and his father.  Ditto for the wife's side.  There is huge amount of material to be covered.  You all have covered parts of it but not comprehensively.
