I have lots of charts to show relationship, but the simplest way I have ever been shown is the "Step Version". You place the relatives on doorsteps like this; Each step is a generation: __Brother-------------------------Sister____ l l ___ Child-----First Cousin-- Child___ l _____Child ------First Cousin once removed If you are not standing on the same step then you are "once removed" or two steps down you are "twice" removed.
