Grab a beverage, this will be lengthy 
#1 I’m going to call “mine”, was a shareboard at the lesson barn. Trainer (not mine) friend suggested him as owner was an absentee who worked as an Aerobics instructor (
this was 1980-something), horse was a wedding gift.
QH gelding from Racing stock, back as long as a school bus, 4yo, bright blood bay w/socks & a snip. I taught him - with my trainer’s help - to jump, showed locally PreGreen & Ammy with some success.
Owner was more than generous, letting me take him to weekend 3-day shows.
On the rare occasion, she’d show up on a Sunday & ride him in the U/S classes.
Then she moved to a distant 'burb & I was back on schoolies for a couple years.
#2 was a 6yo never-raced (racetrack trainer kept him as a Pony) TB plain dark bay gelding, bought through my trainer who had a pipeline to that track.
Her MO was for clients to buy a “starter”, then move up the following year to more horse.
And more comi$$ion for her 
I’d told her straight out this wasn’t my agenda & got her Seller’s asking price down to what I wanted to spend. She took a gamble on less commission & we showed regional Hunters.
That 1st year, mid-season, she told me a local BNT would pay 3X my purchase price for him.
I declined.
A couple years later she held a Diane Carney (then a local BN) clinic at our barn.
Trainer’s Newb Rider sister was then shareboarding my horse & rode him Saturday.
I was working that weekend & couldn’t ride that day.
When I showed up for Sunday, boarders told me my horse had packed sister around, saving her from an involuntary dismount in a Bounce:
“He cantered in place!” I was told.
I rode Sunday, had fun when Diane had us swap horses & I got a Point & Shoot.
Gal who got my horse later told me “I now respect your leg” 
Trainer told me Diane would give me 10X what I’d paid 
I mentally added her 15% to that & seriously considered the offer.
But, I was having too much fun to want to start over.
I had that horse for 20yrs, through 3 more trainers - Hunters, Dressage/Eventing & back to Dressage - 4 more barns, then bought my farm & brought him home.
Where I lost him 5yrs later to a trailering accident 
#3 was really DH’s. Found through a former employee of mine who bought him, got pregnant & couldn’t ride.
TWH, registered Racking, w/o a lot of Gait.
But he was a bold Xcountry horse & his natural Sit & suspension made him a good Dressage prospect.
Sadly I lost him - 2yrs after I lost DH - to a mystery wasting lameness. NQR in October, PTS in February.
#4 was 10yo registered TWHBEA, gelded at 8 with a colt on the ground. 17+h of dark bay. My vet called him The Belgian Walking Horse 
I got him after losing #3 because I worried TB couldn’t be alone on my farm (then under construction). Friend who sold youngstock sold a mare to the BO whose boarder had this horse, she’d bought him as a stud, had him gelded, but he scared her.
Big sweetheart who never trotted, not even in pasture. But his gait was like a backrub & my Dressage trainer was able to work with us, with me doing all the riding, even correcting his tendency to crossfire at canter.
Lost him in the same trailer accident w/TB 
#5 was a COTH Giveaway. 15yo Buckskin Australian WB (Hanoverian stud out of Stock horse mare). Former GP Jumper - COTH poster linked to his show records in Australia as a 6-10yo. Imported to FL, he’d ended up in a Sale barn, where another COTHer bought him for Jr client. But he’d been misused & limited to under 3’ - fine for me.
I had friends near him in FL, flew down to test ride & owner generously let me have him.
We had 5 good years before he developed an anaerobic infection in a hoof capsule. He would have sloughed the hoof & at 19 I wouldn’t put him through that.
#6 was a Freebie. Hackney Pony given to me as a companion by my shoer. Broke to drive, but shoer (with Driving expertise) had crashed & warned me not to drive him.
I’ve ground driven him, but he’s now largely ornamental at 23 last month.
Typical Hackney, he could pass for 5 if his face hadn’t gone so gray 
#7 is an “alleged” TWH (no registration) given to me by a trailriding/horsecamping friend when I lost #5. 16h dark bay with a white nose & leftside socks. He was gaited, but working with my Dressage trainer & me in the irons, he now trots & canter is a Work in Progress.
Budget has forced me to give up my 2X monthly lessons & Lazy has me riding a lot less, but he’s been on rides with my Driving Club & trails.
#8 is my Old Lady Folly - a Driving mini.
At County Fair he & his 1/2 brother were being shown as 2yos in Halter. Friend showing them asked me to help while he clipped. Bro required a Headlock, my guy stood like a rock: ears, muzzle, anywhere. As a pretty new Driver, temperament sold me.
He’ll be 9 next month & Driving friends tell me I’ve won the Mini Lottery.
He has a motor, but is pretty unflappable & fun to drive.
We have CDE aspirations. May never cone to pass, but I’m okay with that.
