absolutely no idea how many either of mine had before me, Flash was bred in Holland and the owner before me bought him from Belgium, so including me at least 4, bless him I bought him as a 4yr old and he'd had at least 3 owners in less than 12 months. He's with me for life.
Breeder, then friend of breeder, then back to breeder, then to a reverend and his wife, then to a lady who sold him at Ashford auction to my friend and then me in 21 years. I have been in touch with all of them and am in regular contact with his breeder who came from Yorks to see him last year and I have his full history including photos!
