Tonya, I'm sorry I forgot to reply to your earlier post, my kids interrupted me.
It is possible that Ron and Samantha are distant cousins.
If Samantha is Ron's sister then she is his very much older sister at age 16.
She does have two brothers and a sister her age who are all black and white cats with black noses and black chin spots and their mother was a pretty young tuxy girl.
Have you posted any recent photos of Ron?
If you did I may have missed them, I would love to see some photos of Ron.
Also just so you know, Samantha does have a boyfriend kitty here at Pet Talk, her sweetie is Tubby.

Thanks for the nice comments Catsnclay and Tonya and Popcornbird.
