I gotta redo this drawing at some point. I under cooked Fiddlesticks, when I think she is a nice design and character, but for now, I'll post it.
I think I'll post a little more lore, since I feel like I missed a conversation last thread.
For me, Octavia's Grandfather had three kids: Octavia's Uncle (the eldest), Octavia's Dad (the middle), and (the youngest) Fiddlesticks. Fiddlesticks is almost 15 years younger than Octavia's Dad when her Grandfather remarried a woman from the Apple Family. Symphonia is Octavia's cousin from her uncle. Although the Apple Family is usually very welcoming, Octavia's Grandfather and his side of the family are from a backcountry place called Blackwater, a bayou by a mountainside remote from Equestria where the land is strange and unkind, where only the desperate, resilient, or crazy go. Only bad things come from that place or so the stories go. Originally the county was unclaimed Gryphon territory where trappers and hunters would come seasonally for some game, hunting gators, bears, and deer. However, some earth ponies migrated there looking for land to cultivate which was leased to them by the Gryphons, since they are only interested in seasonal hunting rights and were alright with being catered by ponies who would tend the land for them. After centuries, it was just some boonies area called Boggy Water that was known for very resilient ponies, but there were tall tales of odd sorts of creatures, like the Dancing Lights, the Talking Tiger, and the Timber Mare. The insolated place, humid weather, and remoteness of it made the place unattractive and poverty of the ponies from there made them ostracized. This prejudice continued for centuries. Then the Blackroot Cult, a group lead by an earth pony shaman, was at its apex during a doomsday scare which pushed them to doing blood sacrifices to the tree spirits. They were ran out of Equestria proper into Boggy Water. When there was a followed up pursuit of the cult, the locals refused to join in, because for centuries they were neglected by their Equestrian counterparts. The cult simmered down and integrated with the locals after the heat was gone, only adding to the animosity the locals from there suffered. Thus the name Blackwater stuck for another century. However, ten years ago, a blue grass singer from Blackwater got multiple songs to hit the top of the charts using local songs, notably the number one hitfor two weeks, Timber Mare. The hostility was gone, but the prejudice didn't die out. Octavia's Grandfather is the only standout exception for achieving success in Canterlot for his background, but the family still is discouraged from naming its roots. The Apple family readily accepts Fiddlesticks as one of their own, but the rest of the family is usually discouraged from associating with them.

How this plays out for Tolltavia's modern interactions with the Apple family hasn't been decided yet.
