Shining Armor's True Family

Hello MLP fans again I have a new theories for and its about Shining Armor. Have you ever notice that Shining Armor looks nothing like his parents and Twlight. Now I will go into story telling mode so you can know who Shining Armor true family. When Twlght's and Shining Armor's parents got married they thought they where't going to have kids. So after a lot of thinking they decided to adopt a baby unicorn. They went to the orphanage to adopt,when the pony who owned the orphanage said they were approved to adopt they were so happy. Then they picked a white unicorn with a blue mane and tail his name was Shining Armor. A few years later Night Light told Shining Armor his mother was going to have a baby girl her name was Twlight Sparkle. Twlight parents never told Shining Armor that he was adopted.
I bet your wondering by now who are Shining Armor's real parents. Well he has a mom,dad,and a sister his mom is a white unicorn with a black mane and tail she used to be a royal guard for princess Celestia. His dad was a black unicorn with a blue mane and tail he played music for the Grand Galloping Gala. The reason they left Shining Armor and his sister at the orphanage because they thought they couldn't take care of them. But Shining Armor's sister live in Ponyville now,she is a white unicorn with a blue mane and tail she is also into music her name is DJ Pon 3. And that's Shining Armor's family.
