What relation is the great grandchild of my grandad's second cousin to me? And can some please exlain the whole cousin and cousin removed thing to me .... in simple terms please? TIA
I'd call it a very distant relation...... Your cousin is the child of your parent's brother or sister.
This chart explains the second cousin stuff http://en.wikipedia.org/wiki/Cousin
Your cousin is the child of your parents brothers and sisters
2nd cousins are the children of grandparents brothers and sisters
your parents cousins would be your cousins once removed.
