She grew up in a normal, loving family, blah blah, really not that interesting until she gets older.
 
Silver started a 2-pony band (her playing acoustic guitar, and Lemon Twist - her best friend at the time - singing) in order to win some cash at a competition. Everypony seemed to love the two of them and they won the competition by a landslide. 
Her friend managed to convince her that they should start an actual band, and after a lot of convincing (Silver was an introvert for a lot of her life), she finally agreed.
 
They wrote songs together, made a few singles and eventually made a real album. They were making music for nearly a year and a half, but partway through, Silver Belle found her true love - a stallion named Forge Ahead. They had nearly nothing in common asides from their love for the acoustic guitar, and she had never even considered dating anypony until then, but somehow they grew close.
 
After one last single, aptly titled ‘This is my Goodbye’, she stopped making music with her friend. She couldn’t handle the pressure of being in a (very small) band, and the thought of ‘going big’ as her friend had said, was too much for her to handle - not to mention the fact that it would take her away from her coltfriend, who she was spending quite a lot of time with at this point. So, she split up the two-pony band.
 
Fast forward a few years (and then a few more - maybe like, 5 or so?) and she’s moved into a sleepy little town on the edge of a peaceful forest with her husband Forge. A foal was on the way, the cozy 1-story cabin with a loft was all paid for, and she couldn’t be happier. Her husband had even landed a job working for the Royal Armory, and although it took him away from home for a couple weeks at a time, they still managed to raise a wonderful child.
 
She’s had a relatively good life - no major events that shook up her world forever. The forest they now live by may not always remain so peaceful, however.
