There you are! Again, welcome! Six is a wonderful number of cats for a family. We have been a large family in the past, but over the years, there are three now, all rescued. Your Simba definitely looks like he has a lot of Maine Coon genes. Here is our beloved Sammi, who left us a few years back. He was 21 and came to our family at 14.
Yes, he was a Brown Patched Tabby Maine Coon man, rescued as a tiny boy from the mean streets of Beverly Hills (!) by his original family, who needed to rehome him when they became elderly and ill. Their friend, also my friend, got us together. Thank you! There are SO many loved ones up there watching over us, and eventually we will all be reunited.
I'm not positive Sammi was "purebred" -- this is what my friend told me. Since "rescued" is my favorite "breed" and my family and I have always done this, I wouldn't care either way. Your Simba does have the conformations and coat coloring, definitely. *Np -- a lot of people think "Sammi" is a female name. It would have been "Sami", a male name, but I did not name him and when I adopt someone who already has a name, I do not change it.*
Do show us photos of him and the rest of your kitties for us to see! 
Looking forward to it. You can start by posting pics of them in this thread.
I'm glad you joined the site and can't wait to meet the rest of your furry feline family. 
Thank you for rescuing sweet Simba. 
Please feel free to post pics as well as check out some of the excellent Articles and available resources.
