Misty had siblings but we don't know how many or much about them. Pied Piper was a stallion on Beebe Ranch and we know he sired other foals. Maureen Beebe said that many of his foals had a saddle marking on their back like he did. Misty's siblings would have been sold by Beebe Ranch rather than the Chincoteague Volunteer Fire Company. The Beebe's sold ponies year round and also held their own sale during Pony Penning.
The King of Assateague There's a possible 1950s half sibling out of Phantom whose name we know and had a small book written about him. The book The King of Assateague by Talmage S. Wilchcher writes of a white stallion who was out of "the famous Phantom of Assateague". The book is written in a fanciful style so it's unknown if this claim is actually true. Photos of the stallion and some of the few facts about him do add some credibility. The King was described as white but appears to be what we now call a double cream dilute. He appears to have the pink skin and blue eyes of double dilutes. Phantom couldn't have had a double dilute with the chestnut pinto Pied Piper so if The King was out of Phantom he was by a different stallion.

Stormy The below 1949 picture of Stormy appears in historian Victoria Pruitt's papers. An accompanying note says that he is Misty's half brother owned by a Mr. Hurley of Seaford, Delaware. Our best guess is he's out of Phantom given he appears to be black. It's also more common for half siblings to be referred to as such when they share the same dam because stallions can sire many foals. His half sister's most famous foal was also named Stormy in 1962.

Other Misty Relatives
Snowball Pam Decharo emailed Misty's Heaven about her pony Snowball. The mare was born in the 1960s and was purchased at Pony Penning. Pam said she was Misty's niece and was sired by an "albino" stallion. This matches up with Snowball being by The King of Assateague if he was indeed a son of Phantom. Snowball was a very successful jumper pony.
Misty II Misty II was a palomino pinto filly who was one of the ponies that played Misty in the movie. The filly appeared in one of the early scenes as a suckling foal. She was described in multiple newspaper articles as a blood relative of Misty. There's no additional description as to how exactly the filly was related to Misty. Perhaps she was a daughter of the King of Assateague as he would have been a stallion at that time. She appeared alongside Misty at the premier of the movie on Chincoteague. The filly wore a tag on her halter at the premier that said "I Am Misty II". The tag matches one that Misty wore in real life and in the children's book Misty the Wonder Pony.
She was to be a gift to a young Caroline Kennedy but that did not happen. Misty II was offered in raffles at an the June 1961 movie premier of at Byrd and State Theaters in Richmond, Virginia and August 1961 carnival in Wilkes-Barre, PA. Misty II made an appearance in Richmond at the Sears store on Broad Street. It's presumed someone won the filly in the raffles. No more is known about her life.
Stormy's most famous daughter was later named Misty II in 1974.

Assateague Relatives of Misty If The King of Assateague was Misty's half brother then some of Misty's nieces and nephews would have been sold at the Pony Penning auction in the 1950s and 1960s.
There were some auction foals attributed to Misty's family who weren't. The Pony Penning auctioneer from 1967 to 1999, Bernie Pleasants, often labeled palomino and buckskin foals from "the Misty line" while auctioning them. He was trying to get people to bid and bid higher to get a good price for the fire company. These foals can't be traced to Misty or any of her family. There were no Misty descendant foals auctioned by the fire company until 2019.
