Chenier,
Renodin is obviously "Renodin".
MTYL created the family "Arnickles Renodin", which is an offshoot of house Renodin. So basically, the two players share what one could call an ancestral family, and are player two different offshoots of that family. This has been done a fair amount before (OOC: Hey do you want to be character X's aunt/uncle/whatever), but this is to a much more dedicated degree, and opens the door for some great RP possibilities IMO!
Hope that clarifies!
