Well kind of. To cut a long story short. My family bred a litter if mini schnauzer about 13 years ago. They were kc reg. I was just wondering if there was a way of finding if any were bred on from the same line and perhaps still.are. Reason for query is mainly curious nostalgia. I was 16 when they were born (birth is a whole different thread) and we kept a dog, Rocky, who I took with me on leaving home. Be died 6 weeks back. Any help always appreciated.

Do you know the kennel names of any of your dogs siblings?  If so you could try Googling them.  They may crop up in a pedigree somewhere on line.
If you don't remember you could contact the Kennel Club and ask if you can still purchase of copy of the Breed Record Supplement for the quarter year that your dear little dog was born and that will list all their names.
There may be more chance of tracing decendents from your dog's sire as most stud dogs are used more than once.  If you Google his name this may lead you to his breeder who may be able to help you in your search.

Thanks for your help. I'll give it a go.
