my brother is doing his ( ours ) and my brother i law is doing his and his wifes ( my wifes sister ) , so it would be fairly easy to put ours together, my brother is always on about it and trys to drag me to get interested in it, its funny as i cannot think of anything less interesting, I knew my grand parents ( all dead now ) and of course my mum and dad, i couldnt care less who my great grandparents were ( unless they were royalty and i am rightfully the king of a country somewhere, the kingdom of disney would be good ) i know its very popular so i must be in the minority with not caring who they were
